Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602470, here are decompositions:

13 + 31602457 = 31602470
19 + 31602451 = 31602470
73 + 31602397 = 31602470
103 + 31602367 = 31602470
307 + 31602163 = 31602470
349 + 31602121 = 31602470
373 + 31602097 = 31602470
421 + 31602049 = 31602470

Showing the first eight; more decompositions exist.
