Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514746, here are decompositions:

5 + 31514741 = 31514746
59 + 31514687 = 31514746
83 + 31514663 = 31514746
167 + 31514579 = 31514746
173 + 31514573 = 31514746
233 + 31514513 = 31514746
269 + 31514477 = 31514746
317 + 31514429 = 31514746

Showing the first eight; more decompositions exist.
