Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546486, here are decompositions:

3 + 31546483 = 31546486
17 + 31546469 = 31546486
29 + 31546457 = 31546486
137 + 31546349 = 31546486
149 + 31546337 = 31546486
269 + 31546217 = 31546486
467 + 31546019 = 31546486
479 + 31546007 = 31546486

Showing the first eight; more decompositions exist.
