Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7042, here are decompositions:

  • 3 + 7039 = 7042
  • 23 + 7019 = 7042
  • 29 + 7013 = 7042
  • 41 + 7001 = 7042
  • 59 + 6983 = 7042
  • 71 + 6971 = 7042
  • 83 + 6959 = 7042
  • 131 + 6911 = 7042

Showing the first eight; more decompositions exist.
