Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547502, here are decompositions:

13 + 31547489 = 31547502
23 + 31547479 = 31547502
31 + 31547471 = 31547502
43 + 31547459 = 31547502
53 + 31547449 = 31547502
61 + 31547441 = 31547502
89 + 31547413 = 31547502
163 + 31547339 = 31547502

Showing the first eight; more decompositions exist.
