Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602570, here are decompositions:

31 + 31602539 = 31602570
53 + 31602517 = 31602570
73 + 31602497 = 31602570
89 + 31602481 = 31602570
113 + 31602457 = 31602570
127 + 31602443 = 31602570
149 + 31602421 = 31602570
173 + 31602397 = 31602570

Showing the first eight; more decompositions exist.
