Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502150, here are decompositions:

3 + 31502147 = 31502150
19 + 31502131 = 31502150
37 + 31502113 = 31502150
67 + 31502083 = 31502150
193 + 31501957 = 31502150
271 + 31501879 = 31502150
331 + 31501819 = 31502150
409 + 31501741 = 31502150

Showing the first eight; more decompositions exist.
