Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8734278, here are decompositions:

19 + 8734259 = 8734278
31 + 8734247 = 8734278
41 + 8734237 = 8734278
67 + 8734211 = 8734278
79 + 8734199 = 8734278
109 + 8734169 = 8734278
131 + 8734147 = 8734278
199 + 8734079 = 8734278

Showing the first eight; more decompositions exist.
