Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624750, here are decompositions:

11 + 31624739 = 31624750
89 + 31624661 = 31624750
107 + 31624643 = 31624750
137 + 31624613 = 31624750
191 + 31624559 = 31624750
239 + 31624511 = 31624750
293 + 31624457 = 31624750
383 + 31624367 = 31624750

Showing the first eight; more decompositions exist.
