Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466546, here are decompositions:

43 + 31466503 = 31466546
157 + 31466389 = 31466546
283 + 31466263 = 31466546
313 + 31466233 = 31466546
373 + 31466173 = 31466546
409 + 31466137 = 31466546
439 + 31466107 = 31466546
457 + 31466089 = 31466546

Showing the first eight; more decompositions exist.
