Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742356, here are decompositions:

3 + 8742353 = 8742356
43 + 8742313 = 8742356
97 + 8742259 = 8742356
163 + 8742193 = 8742356
199 + 8742157 = 8742356
223 + 8742133 = 8742356
367 + 8741989 = 8742356
373 + 8741983 = 8742356

Showing the first eight; more decompositions exist.
