Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460756, here are decompositions:

13 + 31460743 = 31460756
79 + 31460677 = 31460756
109 + 31460647 = 31460756
409 + 31460347 = 31460756
463 + 31460293 = 31460756
619 + 31460137 = 31460756
739 + 31460017 = 31460756
757 + 31459999 = 31460756

Showing the first eight; more decompositions exist.
