Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474248, here are decompositions:

  • 31 + 31474217 = 31474248
  • 107 + 31474141 = 31474248
  • 137 + 31474111 = 31474248
  • 191 + 31474057 = 31474248
  • 241 + 31474007 = 31474248
  • 257 + 31473991 = 31474248
  • 271 + 31473977 = 31474248
  • 277 + 31473971 = 31474248

Showing the first eight; more decompositions exist.
