Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501364, here are decompositions:

3 + 31501361 = 31501364
31 + 31501333 = 31501364
43 + 31501321 = 31501364
61 + 31501303 = 31501364
163 + 31501201 = 31501364
283 + 31501081 = 31501364
397 + 31500967 = 31501364
547 + 31500817 = 31501364

Showing the first eight; more decompositions exist.
