Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514832, here are decompositions:

43 + 31514789 = 31514832
61 + 31514771 = 31514832
101 + 31514731 = 31514832
179 + 31514653 = 31514832
191 + 31514641 = 31514832
233 + 31514599 = 31514832
281 + 31514551 = 31514832
353 + 31514479 = 31514832

Showing the first eight; more decompositions exist.
