Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621254, here are decompositions:

11 + 8621243 = 8621254
17 + 8621237 = 8621254
41 + 8621213 = 8621254
53 + 8621201 = 8621254
71 + 8621183 = 8621254
101 + 8621153 = 8621254
107 + 8621147 = 8621254
167 + 8621087 = 8621254

Showing the first eight; more decompositions exist.
