Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574406, here are decompositions:

37 + 31574369 = 31574406
43 + 31574363 = 31574406
79 + 31574327 = 31574406
103 + 31574303 = 31574406
109 + 31574297 = 31574406
173 + 31574233 = 31574406
233 + 31574173 = 31574406
307 + 31574099 = 31574406

Showing the first eight; more decompositions exist.
