Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574532, here are decompositions:

43 + 31574489 = 31574532
53 + 31574479 = 31574532
79 + 31574453 = 31574532
83 + 31574449 = 31574532
89 + 31574443 = 31574532
103 + 31574429 = 31574532
113 + 31574419 = 31574532
163 + 31574369 = 31574532

Showing the first eight; more decompositions exist.
