Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602518, here are decompositions:

37 + 31602481 = 31602518
61 + 31602457 = 31602518
67 + 31602451 = 31602518
97 + 31602421 = 31602518
151 + 31602367 = 31602518
397 + 31602121 = 31602518
421 + 31602097 = 31602518
439 + 31602079 = 31602518

Showing the first eight; more decompositions exist.
