Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42884, here are decompositions:

  • 31 + 42853 = 42884
  • 43 + 42841 = 42884
  • 97 + 42787 = 42884
  • 157 + 42727 = 42884
  • 181 + 42703 = 42884
  • 241 + 42643 = 42884
  • 307 + 42577 = 42884
  • 313 + 42571 = 42884

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 42884 first appears in π at position 201,821 of the decimal expansion (the 201,821ordinal-suffix:st digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
