Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546328, here are decompositions:

61 + 31546267 = 31546328
97 + 31546231 = 31546328
199 + 31546129 = 31546328
337 + 31545991 = 31546328
409 + 31545919 = 31546328
487 + 31545841 = 31546328
661 + 31545667 = 31546328
829 + 31545499 = 31546328

Showing the first eight; more decompositions exist.
