Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475822, here are decompositions:

43 + 31475779 = 31475822
73 + 31475749 = 31475822
109 + 31475713 = 31475822
139 + 31475683 = 31475822
199 + 31475623 = 31475822
211 + 31475611 = 31475822
223 + 31475599 = 31475822
241 + 31475581 = 31475822

Showing the first eight; more decompositions exist.
