Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100940, here are decompositions:

3 + 100937 = 100940
13 + 100927 = 100940
139 + 100801 = 100940
193 + 100747 = 100940
199 + 100741 = 100940
241 + 100699 = 100940
271 + 100669 = 100940
331 + 100609 = 100940

Showing the first eight; more decompositions exist.
