Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483802, here are decompositions:

3 + 31483799 = 31483802
13 + 31483789 = 31483802
43 + 31483759 = 31483802
79 + 31483723 = 31483802
139 + 31483663 = 31483802
331 + 31483471 = 31483802
349 + 31483453 = 31483802
373 + 31483429 = 31483802

Showing the first eight; more decompositions exist.
