Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577804, here are decompositions:

7 + 31577797 = 31577804
31 + 31577773 = 31577804
157 + 31577647 = 31577804
211 + 31577593 = 31577804
277 + 31577527 = 31577804
283 + 31577521 = 31577804
331 + 31577473 = 31577804
421 + 31577383 = 31577804

Showing the first eight; more decompositions exist.
