Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602330, here are decompositions:

7 + 31602323 = 31602330
13 + 31602317 = 31602330
79 + 31602251 = 31602330
103 + 31602227 = 31602330
113 + 31602217 = 31602330
157 + 31602173 = 31602330
167 + 31602163 = 31602330
233 + 31602097 = 31602330

Showing the first eight; more decompositions exist.
