Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100684, here are decompositions:

11 + 100673 = 100684
71 + 100613 = 100684
137 + 100547 = 100684
167 + 100517 = 100684
173 + 100511 = 100684
191 + 100493 = 100684
281 + 100403 = 100684
293 + 100391 = 100684

Showing the first eight; more decompositions exist.
