Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2058, here are decompositions:

  • 5 + 2053 = 2058
  • 19 + 2039 = 2058
  • 29 + 2029 = 2058
  • 31 + 2027 = 2058
  • 41 + 2017 = 2058
  • 47 + 2011 = 2058
  • 59 + 1999 = 2058
  • 61 + 1997 = 2058

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 2058 first appears in π at position 5,545 of the decimal expansion (the 5,545ordinal-suffix:th 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.
