Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621244, here are decompositions:

7 + 8621237 = 8621244
31 + 8621213 = 8621244
43 + 8621201 = 8621244
61 + 8621183 = 8621244
97 + 8621147 = 8621244
101 + 8621143 = 8621244
157 + 8621087 = 8621244
167 + 8621077 = 8621244

Showing the first eight; more decompositions exist.
