Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504984, here are decompositions:

3 + 31504981 = 31504984
41 + 31504943 = 31504984
101 + 31504883 = 31504984
281 + 31504703 = 31504984
293 + 31504691 = 31504984
317 + 31504667 = 31504984
491 + 31504493 = 31504984
503 + 31504481 = 31504984

Showing the first eight; more decompositions exist.
