Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541254, here are decompositions:

  • 11 + 31541243 = 31541254
  • 113 + 31541141 = 31541254
  • 137 + 31541117 = 31541254
  • 233 + 31541021 = 31541254
  • 263 + 31540991 = 31541254
  • 293 + 31540961 = 31541254
  • 383 + 31540871 = 31541254
  • 431 + 31540823 = 31541254

Showing the first eight; more decompositions exist.
