Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619804, here are decompositions:

3 + 31619801 = 31619804
43 + 31619761 = 31619804
157 + 31619647 = 31619804
193 + 31619611 = 31619804
277 + 31619527 = 31619804
283 + 31619521 = 31619804
397 + 31619407 = 31619804
523 + 31619281 = 31619804

Showing the first eight; more decompositions exist.
