Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463664, here are decompositions:

73 + 31463591 = 31463664
131 + 31463533 = 31463664
137 + 31463527 = 31463664
157 + 31463507 = 31463664
181 + 31463483 = 31463664
257 + 31463407 = 31463664
277 + 31463387 = 31463664
311 + 31463353 = 31463664

Showing the first eight; more decompositions exist.
