Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602654, here are decompositions:

7 + 31602647 = 31602654
23 + 31602631 = 31602654
67 + 31602587 = 31602654
73 + 31602581 = 31602654
137 + 31602517 = 31602654
157 + 31602497 = 31602654
173 + 31602481 = 31602654
197 + 31602457 = 31602654

Showing the first eight; more decompositions exist.
