Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100636, here are decompositions:

23 + 100613 = 100636
89 + 100547 = 100636
113 + 100523 = 100636
167 + 100469 = 100636
233 + 100403 = 100636
257 + 100379 = 100636
293 + 100343 = 100636
443 + 100193 = 100636

Showing the first eight; more decompositions exist.
