Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546690, here are decompositions:

29 + 31546661 = 31546690
53 + 31546637 = 31546690
89 + 31546601 = 31546690
107 + 31546583 = 31546690
137 + 31546553 = 31546690
233 + 31546457 = 31546690
239 + 31546451 = 31546690
269 + 31546421 = 31546690

Showing the first eight; more decompositions exist.
