Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31491362, here are decompositions:

31 + 31491331 = 31491362
73 + 31491289 = 31491362
79 + 31491283 = 31491362
109 + 31491253 = 31491362
163 + 31491199 = 31491362
283 + 31491079 = 31491362
373 + 31490989 = 31491362
379 + 31490983 = 31491362

Showing the first eight; more decompositions exist.
