Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502192, here are decompositions:

3 + 31502189 = 31502192
31 + 31502161 = 31502192
61 + 31502131 = 31502192
79 + 31502113 = 31502192
109 + 31502083 = 31502192
313 + 31501879 = 31502192
331 + 31501861 = 31502192
373 + 31501819 = 31502192

Showing the first eight; more decompositions exist.
