Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502592, here are decompositions:

5 + 31502587 = 31502592
29 + 31502563 = 31502592
31 + 31502561 = 31502592
53 + 31502539 = 31502592
59 + 31502533 = 31502592
103 + 31502489 = 31502592
109 + 31502483 = 31502592
151 + 31502441 = 31502592

Showing the first eight; more decompositions exist.
