Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501702, here are decompositions:

3 + 31501699 = 31501702
41 + 31501661 = 31501702
83 + 31501619 = 31501702
179 + 31501523 = 31501702
269 + 31501433 = 31501702
293 + 31501409 = 31501702
389 + 31501313 = 31501702
503 + 31501199 = 31501702

Showing the first eight; more decompositions exist.
