Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502594, here are decompositions:

  • 7 + 31502587 = 31502594
  • 31 + 31502563 = 31502594
  • 37 + 31502557 = 31502594
  • 61 + 31502533 = 31502594
  • 163 + 31502431 = 31502594
  • 223 + 31502371 = 31502594
  • 241 + 31502353 = 31502594
  • 283 + 31502311 = 31502594

Showing the first eight; more decompositions exist.
