Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495276, here are decompositions:

3 + 31495273 = 31495276
89 + 31495187 = 31495276
167 + 31495109 = 31495276
233 + 31495043 = 31495276
257 + 31495019 = 31495276
353 + 31494923 = 31495276
389 + 31494887 = 31495276
467 + 31494809 = 31495276

Showing the first eight; more decompositions exist.
