Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517592, here are decompositions:

5 + 31517587 = 31517592
13 + 31517579 = 31517592
19 + 31517573 = 31517592
59 + 31517533 = 31517592
101 + 31517491 = 31517592
151 + 31517441 = 31517592
179 + 31517413 = 31517592
181 + 31517411 = 31517592

Showing the first eight; more decompositions exist.
