Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456504, here are decompositions:

3 + 31456501 = 31456504
17 + 31456487 = 31456504
173 + 31456331 = 31456504
227 + 31456277 = 31456504
257 + 31456247 = 31456504
263 + 31456241 = 31456504
311 + 31456193 = 31456504
383 + 31456121 = 31456504

Showing the first eight; more decompositions exist.
