Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502862, here are decompositions:

5 + 31502857 = 31502862
101 + 31502761 = 31502862
163 + 31502699 = 31502862
173 + 31502689 = 31502862
373 + 31502489 = 31502862
379 + 31502483 = 31502862
421 + 31502441 = 31502862
431 + 31502431 = 31502862

Showing the first eight; more decompositions exist.
