Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743242, here are decompositions:

29 + 8743213 = 8743242
73 + 8743169 = 8743242
103 + 8743139 = 8743242
139 + 8743103 = 8743242
163 + 8743079 = 8743242
199 + 8743043 = 8743242
223 + 8743019 = 8743242
241 + 8743001 = 8743242

Showing the first eight; more decompositions exist.
