Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460992, here are decompositions:

41 + 31460951 = 31460992
113 + 31460879 = 31460992
263 + 31460729 = 31460992
383 + 31460609 = 31460992
443 + 31460549 = 31460992
509 + 31460483 = 31460992
593 + 31460399 = 31460992
653 + 31460339 = 31460992

Showing the first eight; more decompositions exist.
