Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602276, here are decompositions:

37 + 31602239 = 31602276
59 + 31602217 = 31602276
103 + 31602173 = 31602276
113 + 31602163 = 31602276
179 + 31602097 = 31602276
197 + 31602079 = 31602276
227 + 31602049 = 31602276
353 + 31601923 = 31602276

Showing the first eight; more decompositions exist.
