Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504796, here are decompositions:

13 + 31504783 = 31504796
223 + 31504573 = 31504796
229 + 31504567 = 31504796
409 + 31504387 = 31504796
439 + 31504357 = 31504796
577 + 31504219 = 31504796
607 + 31504189 = 31504796
613 + 31504183 = 31504796

Showing the first eight; more decompositions exist.
