Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72704, here are decompositions:

3 + 72701 = 72704
31 + 72673 = 72704
43 + 72661 = 72704
61 + 72643 = 72704
127 + 72577 = 72704
157 + 72547 = 72704
211 + 72493 = 72704
223 + 72481 = 72704

Showing the first eight; more decompositions exist.
