Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502134, here are decompositions:

3 + 31502131 = 31502134
5 + 31502129 = 31502134
197 + 31501937 = 31502134
227 + 31501907 = 31502134
311 + 31501823 = 31502134
353 + 31501781 = 31502134
383 + 31501751 = 31502134
701 + 31501433 = 31502134

Showing the first eight; more decompositions exist.
