Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574304, here are decompositions:

7 + 31574297 = 31574304
43 + 31574261 = 31574304
71 + 31574233 = 31574304
101 + 31574203 = 31574304
103 + 31574201 = 31574304
131 + 31574173 = 31574304
173 + 31574131 = 31574304
197 + 31574107 = 31574304

Showing the first eight; more decompositions exist.
