Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100724, here are decompositions:

31 + 100693 = 100724
103 + 100621 = 100724
223 + 100501 = 100724
241 + 100483 = 100724
277 + 100447 = 100724
307 + 100417 = 100724
313 + 100411 = 100724
331 + 100393 = 100724

Showing the first eight; more decompositions exist.
