Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502586, here are decompositions:

23 + 31502563 = 31502586
29 + 31502557 = 31502586
47 + 31502539 = 31502586
53 + 31502533 = 31502586
97 + 31502489 = 31502586
103 + 31502483 = 31502586
127 + 31502459 = 31502586
223 + 31502363 = 31502586

Showing the first eight; more decompositions exist.
