Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624530, here are decompositions:

19 + 31624511 = 31624530
23 + 31624507 = 31624530
53 + 31624477 = 31624530
73 + 31624457 = 31624530
101 + 31624429 = 31624530
107 + 31624423 = 31624530
163 + 31624367 = 31624530
167 + 31624363 = 31624530

Showing the first eight; more decompositions exist.
