Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546420, here are decompositions:

71 + 31546349 = 31546420
83 + 31546337 = 31546420
137 + 31546283 = 31546420
233 + 31546187 = 31546420
239 + 31546181 = 31546420
401 + 31546019 = 31546420
461 + 31545959 = 31546420
467 + 31545953 = 31546420

Showing the first eight; more decompositions exist.
