Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295021520, here are decompositions:

  • 7 + 4295021513 = 4295021520
  • 37 + 4295021483 = 4295021520
  • 67 + 4295021453 = 4295021520
  • 89 + 4295021431 = 4295021520
  • 173 + 4295021347 = 4295021520
  • 193 + 4295021327 = 4295021520
  • 197 + 4295021323 = 4295021520
  • 227 + 4295021293 = 4295021520

Showing the first eight; more decompositions exist.
