Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499876, here are decompositions:

13 + 31499863 = 31499876
43 + 31499833 = 31499876
73 + 31499803 = 31499876
277 + 31499599 = 31499876
283 + 31499593 = 31499876
379 + 31499497 = 31499876
409 + 31499467 = 31499876
547 + 31499329 = 31499876

Showing the first eight; more decompositions exist.
