Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742290, here are decompositions:

31 + 8742259 = 8742290
97 + 8742193 = 8742290
103 + 8742187 = 8742290
157 + 8742133 = 8742290
223 + 8742067 = 8742290
307 + 8741983 = 8742290
313 + 8741977 = 8742290
367 + 8741923 = 8742290

Showing the first eight; more decompositions exist.
