Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502676, here are decompositions:

17 + 31502659 = 31502676
89 + 31502587 = 31502676
113 + 31502563 = 31502676
137 + 31502539 = 31502676
193 + 31502483 = 31502676
313 + 31502363 = 31502676
347 + 31502329 = 31502676
389 + 31502287 = 31502676

Showing the first eight; more decompositions exist.
