Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576766, here are decompositions:

7 + 31576759 = 31576766
127 + 31576639 = 31576766
283 + 31576483 = 31576766
307 + 31576459 = 31576766
313 + 31576453 = 31576766
349 + 31576417 = 31576766
499 + 31576267 = 31576766
547 + 31576219 = 31576766

Showing the first eight; more decompositions exist.
