Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100668, here are decompositions:

19 + 100649 = 100668
47 + 100621 = 100668
59 + 100609 = 100668
109 + 100559 = 100668
131 + 100537 = 100668
149 + 100519 = 100668
151 + 100517 = 100668
157 + 100511 = 100668

Showing the first eight; more decompositions exist.
