Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742254, here are decompositions:

61 + 8742193 = 8742254
67 + 8742187 = 8742254
97 + 8742157 = 8742254
151 + 8742103 = 8742254
271 + 8741983 = 8742254
277 + 8741977 = 8742254
307 + 8741947 = 8742254
331 + 8741923 = 8742254

Showing the first eight; more decompositions exist.
