Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504118, here are decompositions:

31 + 31504087 = 31504118
67 + 31504051 = 31504118
157 + 31503961 = 31504118
271 + 31503847 = 31504118
277 + 31503841 = 31504118
307 + 31503811 = 31504118
367 + 31503751 = 31504118
487 + 31503631 = 31504118

Showing the first eight; more decompositions exist.
