Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502922, here are decompositions:

41 + 31502881 = 31502922
179 + 31502743 = 31502922
223 + 31502699 = 31502922
233 + 31502689 = 31502922
263 + 31502659 = 31502922
359 + 31502563 = 31502922
383 + 31502539 = 31502922
389 + 31502533 = 31502922

Showing the first eight; more decompositions exist.
