Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542494, here are decompositions:

  • 7 + 31542487 = 31542494
  • 37 + 31542457 = 31542494
  • 97 + 31542397 = 31542494
  • 103 + 31542391 = 31542494
  • 331 + 31542163 = 31542494
  • 457 + 31542037 = 31542494
  • 463 + 31542031 = 31542494
  • 523 + 31541971 = 31542494

Showing the first eight; more decompositions exist.
