Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31487326, here are decompositions:

47 + 31487279 = 31487326
173 + 31487153 = 31487326
179 + 31487147 = 31487326
239 + 31487087 = 31487326
263 + 31487063 = 31487326
293 + 31487033 = 31487326
359 + 31486967 = 31487326
467 + 31486859 = 31487326

Showing the first eight; more decompositions exist.
