Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502330, here are decompositions:

19 + 31502311 = 31502330
43 + 31502287 = 31502330
61 + 31502269 = 31502330
199 + 31502131 = 31502330
373 + 31501957 = 31502330
499 + 31501831 = 31502330
523 + 31501807 = 31502330
571 + 31501759 = 31502330

Showing the first eight; more decompositions exist.
