Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100518, here are decompositions:

7 + 100511 = 100518
17 + 100501 = 100518
59 + 100459 = 100518
71 + 100447 = 100518
101 + 100417 = 100518
107 + 100411 = 100518
127 + 100391 = 100518
139 + 100379 = 100518

Showing the first eight; more decompositions exist.
