Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490996, here are decompositions:

7 + 31490989 = 31490996
13 + 31490983 = 31490996
79 + 31490917 = 31490996
139 + 31490857 = 31490996
223 + 31490773 = 31490996
283 + 31490713 = 31490996
337 + 31490659 = 31490996
367 + 31490629 = 31490996

Showing the first eight; more decompositions exist.
