Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742246, here are decompositions:

53 + 8742193 = 8742246
59 + 8742187 = 8742246
89 + 8742157 = 8742246
113 + 8742133 = 8742246
179 + 8742067 = 8742246
257 + 8741989 = 8742246
263 + 8741983 = 8742246
269 + 8741977 = 8742246

Showing the first eight; more decompositions exist.
