Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502194, here are decompositions:

5 + 31502189 = 31502194
11 + 31502183 = 31502194
47 + 31502147 = 31502194
257 + 31501937 = 31502194
281 + 31501913 = 31502194
443 + 31501751 = 31502194
467 + 31501727 = 31502194
761 + 31501433 = 31502194

Showing the first eight; more decompositions exist.
