Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623028, here are decompositions:

151 + 8622877 = 8623028
157 + 8622871 = 8623028
181 + 8622847 = 8623028
307 + 8622721 = 8623028
499 + 8622529 = 8623028
541 + 8622487 = 8623028
607 + 8622421 = 8623028
691 + 8622337 = 8623028

Showing the first eight; more decompositions exist.
