Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628958, here are decompositions:

59 + 8628899 = 8628958
101 + 8628857 = 8628958
167 + 8628791 = 8628958
179 + 8628779 = 8628958
281 + 8628677 = 8628958
311 + 8628647 = 8628958
479 + 8628479 = 8628958
509 + 8628449 = 8628958

Showing the first eight; more decompositions exist.
