Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602628, here are decompositions:

41 + 31602587 = 31602628
47 + 31602581 = 31602628
89 + 31602539 = 31602628
107 + 31602521 = 31602628
131 + 31602497 = 31602628
227 + 31602401 = 31602628
311 + 31602317 = 31602628
347 + 31602281 = 31602628

Showing the first eight; more decompositions exist.
