Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463652, here are decompositions:

61 + 31463591 = 31463652
163 + 31463489 = 31463652
193 + 31463459 = 31463652
223 + 31463429 = 31463652
263 + 31463389 = 31463652
331 + 31463321 = 31463652
383 + 31463269 = 31463652
439 + 31463213 = 31463652

Showing the first eight; more decompositions exist.
