Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546774, here are decompositions:

53 + 31546721 = 31546774
113 + 31546661 = 31546774
137 + 31546637 = 31546774
173 + 31546601 = 31546774
191 + 31546583 = 31546774
317 + 31546457 = 31546774
353 + 31546421 = 31546774
491 + 31546283 = 31546774

Showing the first eight; more decompositions exist.
