Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502652, here are decompositions:

89 + 31502563 = 31502652
113 + 31502539 = 31502652
163 + 31502489 = 31502652
193 + 31502459 = 31502652
211 + 31502441 = 31502652
281 + 31502371 = 31502652
373 + 31502279 = 31502652
383 + 31502269 = 31502652

Showing the first eight; more decompositions exist.
