Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602738, here are decompositions:

47 + 31602691 = 31602738
59 + 31602679 = 31602738
107 + 31602631 = 31602738
149 + 31602589 = 31602738
151 + 31602587 = 31602738
157 + 31602581 = 31602738
199 + 31602539 = 31602738
241 + 31602497 = 31602738

Showing the first eight; more decompositions exist.
