Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72742, here are decompositions:

3 + 72739 = 72742
23 + 72719 = 72742
41 + 72701 = 72742
53 + 72689 = 72742
71 + 72671 = 72742
191 + 72551 = 72742
239 + 72503 = 72742
281 + 72461 = 72742

Showing the first eight; more decompositions exist.
