Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690318, here are decompositions:

97 + 8690221 = 8690318
127 + 8690191 = 8690318
199 + 8690119 = 8690318
229 + 8690089 = 8690318
277 + 8690041 = 8690318
331 + 8689987 = 8690318
337 + 8689981 = 8690318
349 + 8689969 = 8690318

Showing the first eight; more decompositions exist.
