Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624460, here are decompositions:

3 + 31624457 = 31624460
31 + 31624429 = 31624460
37 + 31624423 = 31624460
73 + 31624387 = 31624460
97 + 31624363 = 31624460
103 + 31624357 = 31624460
139 + 31624321 = 31624460
313 + 31624147 = 31624460

Showing the first eight; more decompositions exist.
