Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602980, here are decompositions:

7 + 31602973 = 31602980
103 + 31602877 = 31602980
127 + 31602853 = 31602980
307 + 31602673 = 31602980
349 + 31602631 = 31602980
463 + 31602517 = 31602980
499 + 31602481 = 31602980
523 + 31602457 = 31602980

Showing the first eight; more decompositions exist.
