Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574470, here are decompositions:

3 + 31574467 = 31574470
17 + 31574453 = 31574470
41 + 31574429 = 31574470
101 + 31574369 = 31574470
107 + 31574363 = 31574470
167 + 31574303 = 31574470
173 + 31574297 = 31574470
269 + 31574201 = 31574470

Showing the first eight; more decompositions exist.
