Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658992, here are decompositions:

3 + 8658989 = 8658992
31 + 8658961 = 8658992
61 + 8658931 = 8658992
73 + 8658919 = 8658992
163 + 8658829 = 8658992
283 + 8658709 = 8658992
313 + 8658679 = 8658992
373 + 8658619 = 8658992

Showing the first eight; more decompositions exist.
