Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626120, here are decompositions:

11 + 8626109 = 8626120
17 + 8626103 = 8626120
53 + 8626067 = 8626120
59 + 8626061 = 8626120
137 + 8625983 = 8626120
311 + 8625809 = 8626120
431 + 8625689 = 8626120
479 + 8625641 = 8626120

Showing the first eight; more decompositions exist.
