Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100646, here are decompositions:

37 + 100609 = 100646
97 + 100549 = 100646
109 + 100537 = 100646
127 + 100519 = 100646
163 + 100483 = 100646
199 + 100447 = 100646
229 + 100417 = 100646
283 + 100363 = 100646

Showing the first eight; more decompositions exist.
