Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528626, here are decompositions:

3 + 528623 = 528626
67 + 528559 = 528626
139 + 528487 = 528626
157 + 528469 = 528626
193 + 528433 = 528626
223 + 528403 = 528626
313 + 528313 = 528626
337 + 528289 = 528626

Showing the first eight; more decompositions exist.
