Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472646, here are decompositions:

13 + 31472633 = 31472646
59 + 31472587 = 31472646
109 + 31472537 = 31472646
157 + 31472489 = 31472646
167 + 31472479 = 31472646
197 + 31472449 = 31472646
307 + 31472339 = 31472646
353 + 31472293 = 31472646

Showing the first eight; more decompositions exist.
