Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690288, here are decompositions:

67 + 8690221 = 8690288
97 + 8690191 = 8690288
199 + 8690089 = 8690288
307 + 8689981 = 8690288
331 + 8689957 = 8690288
577 + 8689711 = 8690288
601 + 8689687 = 8690288
631 + 8689657 = 8690288

Showing the first eight; more decompositions exist.
