Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645452, here are decompositions:

3 + 8645449 = 8645452
71 + 8645381 = 8645452
191 + 8645261 = 8645452
311 + 8645141 = 8645452
443 + 8645009 = 8645452
461 + 8644991 = 8645452
503 + 8644949 = 8645452
653 + 8644799 = 8645452

Showing the first eight; more decompositions exist.
