Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147560042, here are decompositions:

  • 3 + 2147560039 = 2147560042
  • 53 + 2147559989 = 2147560042
  • 101 + 2147559941 = 2147560042
  • 281 + 2147559761 = 2147560042
  • 479 + 2147559563 = 2147560042
  • 503 + 2147559539 = 2147560042
  • 521 + 2147559521 = 2147560042
  • 659 + 2147559383 = 2147560042

Showing the first eight; more decompositions exist.
