Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514690, here are decompositions:

3 + 31514687 = 31514690
19 + 31514671 = 31514690
37 + 31514653 = 31514690
61 + 31514629 = 31514690
139 + 31514551 = 31514690
157 + 31514533 = 31514690
211 + 31514479 = 31514690
241 + 31514449 = 31514690

Showing the first eight; more decompositions exist.
