Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470590, here are decompositions:

  • 43 + 31470547 = 31470590
  • 181 + 31470409 = 31470590
  • 211 + 31470379 = 31470590
  • 331 + 31470259 = 31470590
  • 367 + 31470223 = 31470590
  • 373 + 31470217 = 31470590
  • 397 + 31470193 = 31470590
  • 439 + 31470151 = 31470590

Showing the first eight; more decompositions exist.
