Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504612, here are decompositions:

5 + 31504607 = 31504612
131 + 31504481 = 31504612
173 + 31504439 = 31504612
239 + 31504373 = 31504612
383 + 31504229 = 31504612
479 + 31504133 = 31504612
509 + 31504103 = 31504612
599 + 31504013 = 31504612

Showing the first eight; more decompositions exist.
