Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492544, here are decompositions:

3 + 31492541 = 31492544
7 + 31492537 = 31492544
67 + 31492477 = 31492544
73 + 31492471 = 31492544
151 + 31492393 = 31492544
283 + 31492261 = 31492544
331 + 31492213 = 31492544
463 + 31492081 = 31492544

Showing the first eight; more decompositions exist.
