Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463626, here are decompositions:

107 + 31463519 = 31463626
137 + 31463489 = 31463626
149 + 31463477 = 31463626
167 + 31463459 = 31463626
197 + 31463429 = 31463626
239 + 31463387 = 31463626
263 + 31463363 = 31463626
479 + 31463147 = 31463626

Showing the first eight; more decompositions exist.
