Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523532, here are decompositions:

11 + 31523521 = 31523532
59 + 31523473 = 31523532
71 + 31523461 = 31523532
113 + 31523419 = 31523532
151 + 31523381 = 31523532
223 + 31523309 = 31523532
239 + 31523293 = 31523532
281 + 31523251 = 31523532

Showing the first eight; more decompositions exist.
