Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492364, here are decompositions:

103 + 31492261 = 31492364
151 + 31492213 = 31492364
271 + 31492093 = 31492364
283 + 31492081 = 31492364
313 + 31492051 = 31492364
331 + 31492033 = 31492364
523 + 31491841 = 31492364
571 + 31491793 = 31492364

Showing the first eight; more decompositions exist.
