Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514704, here are decompositions:

17 + 31514687 = 31514704
41 + 31514663 = 31514704
131 + 31514573 = 31514704
167 + 31514537 = 31514704
191 + 31514513 = 31514704
227 + 31514477 = 31514704
281 + 31514423 = 31514704
443 + 31514261 = 31514704

Showing the first eight; more decompositions exist.
