Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502132, here are decompositions:

3 + 31502129 = 31502132
19 + 31502113 = 31502132
271 + 31501861 = 31502132
283 + 31501849 = 31502132
313 + 31501819 = 31502132
373 + 31501759 = 31502132
433 + 31501699 = 31502132
463 + 31501669 = 31502132

Showing the first eight; more decompositions exist.
