Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602974, here are decompositions:

43 + 31602931 = 31602974
97 + 31602877 = 31602974
181 + 31602793 = 31602974
211 + 31602763 = 31602974
283 + 31602691 = 31602974
313 + 31602661 = 31602974
457 + 31602517 = 31602974
523 + 31602451 = 31602974

Showing the first eight; more decompositions exist.
