Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502636, here are decompositions:

73 + 31502563 = 31502636
79 + 31502557 = 31502636
97 + 31502539 = 31502636
103 + 31502533 = 31502636
283 + 31502353 = 31502636
307 + 31502329 = 31502636
349 + 31502287 = 31502636
367 + 31502269 = 31502636

Showing the first eight; more decompositions exist.
