Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502102, here are decompositions:

3 + 31502099 = 31502102
19 + 31502083 = 31502102
223 + 31501879 = 31502102
241 + 31501861 = 31502102
271 + 31501831 = 31502102
283 + 31501819 = 31502102
433 + 31501669 = 31502102
571 + 31501531 = 31502102

Showing the first eight; more decompositions exist.
