Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502246, here are decompositions:

3 + 31502243 = 31502246
163 + 31502083 = 31502246
367 + 31501879 = 31502246
397 + 31501849 = 31502246
439 + 31501807 = 31502246
487 + 31501759 = 31502246
547 + 31501699 = 31502246
577 + 31501669 = 31502246

Showing the first eight; more decompositions exist.
