Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576826, here are decompositions:

67 + 31576759 = 31576826
277 + 31576549 = 31576826
349 + 31576477 = 31576826
367 + 31576459 = 31576826
373 + 31576453 = 31576826
409 + 31576417 = 31576826
607 + 31576219 = 31576826
709 + 31576117 = 31576826

Showing the first eight; more decompositions exist.
