Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504804, here are decompositions:

3 + 31504801 = 31504804
5 + 31504799 = 31504804
101 + 31504703 = 31504804
113 + 31504691 = 31504804
137 + 31504667 = 31504804
197 + 31504607 = 31504804
257 + 31504547 = 31504804
311 + 31504493 = 31504804

Showing the first eight; more decompositions exist.
