Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508592, here are decompositions:

13 + 31508579 = 31508592
23 + 31508569 = 31508592
43 + 31508549 = 31508592
83 + 31508509 = 31508592
131 + 31508461 = 31508592
139 + 31508453 = 31508592
149 + 31508443 = 31508592
229 + 31508363 = 31508592

Showing the first eight; more decompositions exist.
