Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547822, here are decompositions:

73 + 31547749 = 31547822
139 + 31547683 = 31547822
151 + 31547671 = 31547822
181 + 31547641 = 31547822
193 + 31547629 = 31547822
283 + 31547539 = 31547822
373 + 31547449 = 31547822
409 + 31547413 = 31547822

Showing the first eight; more decompositions exist.
