Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543574, here are decompositions:

  • 3 + 31543571 = 31543574
  • 31 + 31543543 = 31543574
  • 43 + 31543531 = 31543574
  • 331 + 31543243 = 31543574
  • 367 + 31543207 = 31543574
  • 607 + 31542967 = 31543574
  • 631 + 31542943 = 31543574
  • 787 + 31542787 = 31543574

Showing the first eight; more decompositions exist.
