Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699642, here are decompositions:

31 + 8699611 = 8699642
103 + 8699539 = 8699642
109 + 8699533 = 8699642
199 + 8699443 = 8699642
223 + 8699419 = 8699642
229 + 8699413 = 8699642
331 + 8699311 = 8699642
349 + 8699293 = 8699642

Showing the first eight; more decompositions exist.
