Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576610, here are decompositions:

31 + 31576579 = 31576610
61 + 31576549 = 31576610
127 + 31576483 = 31576610
151 + 31576459 = 31576610
157 + 31576453 = 31576610
193 + 31576417 = 31576610
199 + 31576411 = 31576610
349 + 31576261 = 31576610

Showing the first eight; more decompositions exist.
