Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45042, here are decompositions:

  • 29 + 45013 = 45042
  • 59 + 44983 = 45042
  • 71 + 44971 = 45042
  • 79 + 44963 = 45042
  • 83 + 44959 = 45042
  • 89 + 44953 = 45042
  • 103 + 44939 = 45042
  • 149 + 44893 = 45042

Showing the first eight; more decompositions exist.
