Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602740, here are decompositions:

61 + 31602679 = 31602740
67 + 31602673 = 31602740
79 + 31602661 = 31602740
109 + 31602631 = 31602740
151 + 31602589 = 31602740
223 + 31602517 = 31602740
283 + 31602457 = 31602740
373 + 31602367 = 31602740

Showing the first eight; more decompositions exist.
