Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460684, here are decompositions:

7 + 31460677 = 31460684
37 + 31460647 = 31460684
103 + 31460581 = 31460684
193 + 31460491 = 31460684
271 + 31460413 = 31460684
337 + 31460347 = 31460684
421 + 31460263 = 31460684
487 + 31460197 = 31460684

Showing the first eight; more decompositions exist.
