Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602128, here are decompositions:

7 + 31602121 = 31602128
31 + 31602097 = 31602128
79 + 31602049 = 31602128
421 + 31601707 = 31602128
457 + 31601671 = 31602128
499 + 31601629 = 31602128
577 + 31601551 = 31602128
601 + 31601527 = 31602128

Showing the first eight; more decompositions exist.
