Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465084, here are decompositions:

23 + 31465061 = 31465084
137 + 31464947 = 31465084
257 + 31464827 = 31465084
263 + 31464821 = 31465084
353 + 31464731 = 31465084
383 + 31464701 = 31465084
467 + 31464617 = 31465084
503 + 31464581 = 31465084

Showing the first eight; more decompositions exist.
