Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72750, here are decompositions:

11 + 72739 = 72750
17 + 72733 = 72750
23 + 72727 = 72750
31 + 72719 = 72750
43 + 72707 = 72750
61 + 72689 = 72750
71 + 72679 = 72750
79 + 72671 = 72750

Showing the first eight; more decompositions exist.
