Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546162, here are decompositions:

  • 3 + 31546159 = 31546162
  • 149 + 31546013 = 31546162
  • 239 + 31545923 = 31546162
  • 419 + 31545743 = 31546162
  • 449 + 31545713 = 31546162
  • 521 + 31545641 = 31546162
  • 563 + 31545599 = 31546162
  • 761 + 31545401 = 31546162

Showing the first eight; more decompositions exist.
