Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523552, here are decompositions:

13 + 31523539 = 31523552
31 + 31523521 = 31523552
79 + 31523473 = 31523552
223 + 31523329 = 31523552
331 + 31523221 = 31523552
409 + 31523143 = 31523552
421 + 31523131 = 31523552
433 + 31523119 = 31523552

Showing the first eight; more decompositions exist.
