Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463262, here are decompositions:

13 + 31463249 = 31463262
59 + 31463203 = 31463262
101 + 31463161 = 31463262
139 + 31463123 = 31463262
163 + 31463099 = 31463262
179 + 31463083 = 31463262
199 + 31463063 = 31463262
239 + 31463023 = 31463262

Showing the first eight; more decompositions exist.
