Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502708, here are decompositions:

7 + 31502701 = 31502708
19 + 31502689 = 31502708
151 + 31502557 = 31502708
277 + 31502431 = 31502708
337 + 31502371 = 31502708
379 + 31502329 = 31502708
397 + 31502311 = 31502708
421 + 31502287 = 31502708

Showing the first eight; more decompositions exist.
