Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514926, here are decompositions:

89 + 31514837 = 31514926
137 + 31514789 = 31514926
239 + 31514687 = 31514926
263 + 31514663 = 31514926
347 + 31514579 = 31514926
353 + 31514573 = 31514926
389 + 31514537 = 31514926
449 + 31514477 = 31514926

Showing the first eight; more decompositions exist.
