Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507544, here are decompositions:

37 + 31507507 = 31507544
181 + 31507363 = 31507544
193 + 31507351 = 31507544
223 + 31507321 = 31507544
457 + 31507087 = 31507544
463 + 31507081 = 31507544
571 + 31506973 = 31507544
613 + 31506931 = 31507544

Showing the first eight; more decompositions exist.
