Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490036, here are decompositions:

13 + 31490023 = 31490036
37 + 31489999 = 31490036
73 + 31489963 = 31490036
157 + 31489879 = 31490036
163 + 31489873 = 31490036
283 + 31489753 = 31490036
313 + 31489723 = 31490036
373 + 31489663 = 31490036

Showing the first eight; more decompositions exist.
