Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72472, here are decompositions:

3 + 72469 = 72472
5 + 72467 = 72472
11 + 72461 = 72472
41 + 72431 = 72472
89 + 72383 = 72472
131 + 72341 = 72472
251 + 72221 = 72472
311 + 72161 = 72472

Showing the first eight; more decompositions exist.
