Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602428, here are decompositions:

7 + 31602421 = 31602428
31 + 31602397 = 31602428
61 + 31602367 = 31602428
211 + 31602217 = 31602428
307 + 31602121 = 31602428
331 + 31602097 = 31602428
349 + 31602079 = 31602428
379 + 31602049 = 31602428

Showing the first eight; more decompositions exist.
