Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602630, here are decompositions:

41 + 31602589 = 31602630
43 + 31602587 = 31602630
109 + 31602521 = 31602630
113 + 31602517 = 31602630
149 + 31602481 = 31602630
173 + 31602457 = 31602630
179 + 31602451 = 31602630
229 + 31602401 = 31602630

Showing the first eight; more decompositions exist.
