Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550592, here are decompositions:

5 + 31550587 = 31550592
11 + 31550581 = 31550592
19 + 31550573 = 31550592
23 + 31550569 = 31550592
53 + 31550539 = 31550592
61 + 31550531 = 31550592
83 + 31550509 = 31550592
113 + 31550479 = 31550592

Showing the first eight; more decompositions exist.
