Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574244, here are decompositions:

11 + 31574233 = 31574244
41 + 31574203 = 31574244
43 + 31574201 = 31574244
71 + 31574173 = 31574244
113 + 31574131 = 31574244
137 + 31574107 = 31574244
151 + 31574093 = 31574244
173 + 31574071 = 31574244

Showing the first eight; more decompositions exist.
