Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504826, here are decompositions:

7 + 31504819 = 31504826
43 + 31504783 = 31504826
79 + 31504747 = 31504826
373 + 31504453 = 31504826
439 + 31504387 = 31504826
499 + 31504327 = 31504826
523 + 31504303 = 31504826
607 + 31504219 = 31504826

Showing the first eight; more decompositions exist.
