Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492088, here are decompositions:

7 + 31492081 = 31492088
37 + 31492051 = 31492088
409 + 31491679 = 31492088
499 + 31491589 = 31492088
541 + 31491547 = 31492088
577 + 31491511 = 31492088
619 + 31491469 = 31492088
757 + 31491331 = 31492088

Showing the first eight; more decompositions exist.
