Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523544, here are decompositions:

5 + 31523539 = 31523544
7 + 31523537 = 31523544
23 + 31523521 = 31523544
67 + 31523477 = 31523544
71 + 31523473 = 31523544
83 + 31523461 = 31523544
103 + 31523441 = 31523544
137 + 31523407 = 31523544

Showing the first eight; more decompositions exist.
