Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472616, here are decompositions:

5 + 31472611 = 31472616
29 + 31472587 = 31472616
79 + 31472537 = 31472616
127 + 31472489 = 31472616
137 + 31472479 = 31472616
167 + 31472449 = 31472616
179 + 31472437 = 31472616
257 + 31472359 = 31472616

Showing the first eight; more decompositions exist.
