Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592672, here are decompositions:

31 + 31592641 = 31592672
73 + 31592599 = 31592672
283 + 31592389 = 31592672
499 + 31592173 = 31592672
523 + 31592149 = 31592672
619 + 31592053 = 31592672
673 + 31591999 = 31592672
829 + 31591843 = 31592672

Showing the first eight; more decompositions exist.
