Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690018, here are decompositions:

31 + 8689987 = 8690018
37 + 8689981 = 8690018
61 + 8689957 = 8690018
241 + 8689777 = 8690018
307 + 8689711 = 8690018
331 + 8689687 = 8690018
409 + 8689609 = 8690018
619 + 8689399 = 8690018

Showing the first eight; more decompositions exist.
