Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463650, here are decompositions:

59 + 31463591 = 31463650
131 + 31463519 = 31463650
167 + 31463483 = 31463650
173 + 31463477 = 31463650
191 + 31463459 = 31463650
263 + 31463387 = 31463650
389 + 31463261 = 31463650
401 + 31463249 = 31463650

Showing the first eight; more decompositions exist.
