Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507244, here are decompositions:

127 + 31507117 = 31507244
157 + 31507087 = 31507244
163 + 31507081 = 31507244
271 + 31506973 = 31507244
313 + 31506931 = 31507244
337 + 31506907 = 31507244
421 + 31506823 = 31507244
463 + 31506781 = 31507244

Showing the first eight; more decompositions exist.
