Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45000, here are decompositions:

  • 13 + 44987 = 45000
  • 17 + 44983 = 45000
  • 29 + 44971 = 45000
  • 37 + 44963 = 45000
  • 41 + 44959 = 45000
  • 47 + 44953 = 45000
  • 61 + 44939 = 45000
  • 73 + 44927 = 45000

Showing the first eight; more decompositions exist.
