Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495334, here are decompositions:

61 + 31495273 = 31495334
163 + 31495171 = 31495334
181 + 31495153 = 31495334
271 + 31495063 = 31495334
331 + 31495003 = 31495334
397 + 31494937 = 31495334
571 + 31494763 = 31495334
613 + 31494721 = 31495334

Showing the first eight; more decompositions exist.
