Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514762, here are decompositions:

31 + 31514731 = 31514762
73 + 31514689 = 31514762
109 + 31514653 = 31514762
163 + 31514599 = 31514762
211 + 31514551 = 31514762
229 + 31514533 = 31514762
283 + 31514479 = 31514762
313 + 31514449 = 31514762

Showing the first eight; more decompositions exist.
