Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488596, here are decompositions:

103 + 31488493 = 31488596
127 + 31488469 = 31488596
163 + 31488433 = 31488596
463 + 31488133 = 31488596
487 + 31488109 = 31488596
577 + 31488019 = 31488596
619 + 31487977 = 31488596
1069 + 31487527 = 31488596

Showing the first eight; more decompositions exist.
