Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538940, here are decompositions:

13 + 538927 = 538940
19 + 538921 = 538940
139 + 538801 = 538940
151 + 538789 = 538940
163 + 538777 = 538940
229 + 538711 = 538940
373 + 538567 = 538940
379 + 538561 = 538940

Showing the first eight; more decompositions exist.
