Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100538, here are decompositions:

19 + 100519 = 100538
37 + 100501 = 100538
79 + 100459 = 100538
127 + 100411 = 100538
181 + 100357 = 100538
241 + 100297 = 100538
271 + 100267 = 100538
331 + 100207 = 100538

Showing the first eight; more decompositions exist.
