Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544450, here are decompositions:

  • 79 + 31544371 = 31544450
  • 103 + 31544347 = 31544450
  • 127 + 31544323 = 31544450
  • 139 + 31544311 = 31544450
  • 229 + 31544221 = 31544450
  • 271 + 31544179 = 31544450
  • 283 + 31544167 = 31544450
  • 373 + 31544077 = 31544450

Showing the first eight; more decompositions exist.
