Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502026, here are decompositions:

47 + 31501979 = 31502026
89 + 31501937 = 31502026
113 + 31501913 = 31502026
443 + 31501583 = 31502026
503 + 31501523 = 31502026
593 + 31501433 = 31502026
599 + 31501427 = 31502026
617 + 31501409 = 31502026

Showing the first eight; more decompositions exist.
