Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492652, here are decompositions:

181 + 31492471 = 31492652
199 + 31492453 = 31492652
223 + 31492429 = 31492652
229 + 31492423 = 31492652
283 + 31492369 = 31492652
409 + 31492243 = 31492652
439 + 31492213 = 31492652
571 + 31492081 = 31492652

Showing the first eight; more decompositions exist.
