Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658080, here are decompositions:

37 + 8658043 = 8658080
97 + 8657983 = 8658080
157 + 8657923 = 8658080
199 + 8657881 = 8658080
229 + 8657851 = 8658080
313 + 8657767 = 8658080
349 + 8657731 = 8658080
523 + 8657557 = 8658080

Showing the first eight; more decompositions exist.
