Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506504, here are decompositions:

61 + 31506443 = 31506504
67 + 31506437 = 31506504
83 + 31506421 = 31506504
131 + 31506373 = 31506504
137 + 31506367 = 31506504
151 + 31506353 = 31506504
173 + 31506331 = 31506504
193 + 31506311 = 31506504

Showing the first eight; more decompositions exist.
