Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523484, here are decompositions:

7 + 31523477 = 31523484
11 + 31523473 = 31523484
17 + 31523467 = 31523484
23 + 31523461 = 31523484
43 + 31523441 = 31523484
73 + 31523411 = 31523484
103 + 31523381 = 31523484
137 + 31523347 = 31523484

Showing the first eight; more decompositions exist.
