Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621452, here are decompositions:

23 + 8621429 = 8621452
41 + 8621411 = 8621452
113 + 8621339 = 8621452
239 + 8621213 = 8621452
251 + 8621201 = 8621452
263 + 8621189 = 8621452
269 + 8621183 = 8621452
401 + 8621051 = 8621452

Showing the first eight; more decompositions exist.
