Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648248, here are decompositions:

137 + 8648111 = 8648248
149 + 8648099 = 8648248
251 + 8647997 = 8648248
269 + 8647979 = 8648248
281 + 8647967 = 8648248
311 + 8647937 = 8648248
359 + 8647889 = 8648248
431 + 8647817 = 8648248

Showing the first eight; more decompositions exist.
