Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624524, here are decompositions:

13 + 31624511 = 31624524
17 + 31624507 = 31624524
47 + 31624477 = 31624524
67 + 31624457 = 31624524
101 + 31624423 = 31624524
137 + 31624387 = 31624524
157 + 31624367 = 31624524
167 + 31624357 = 31624524

Showing the first eight; more decompositions exist.
