Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574536, here are decompositions:

5 + 31574531 = 31574536
29 + 31574507 = 31574536
47 + 31574489 = 31574536
83 + 31574453 = 31574536
107 + 31574429 = 31574536
167 + 31574369 = 31574536
173 + 31574363 = 31574536
233 + 31574303 = 31574536

Showing the first eight; more decompositions exist.
