Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743212, here are decompositions:

43 + 8743169 = 8743212
73 + 8743139 = 8743212
109 + 8743103 = 8743212
113 + 8743099 = 8743212
193 + 8743019 = 8743212
211 + 8743001 = 8743212
239 + 8742973 = 8743212
271 + 8742941 = 8743212

Showing the first eight; more decompositions exist.
