Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540790, here are decompositions:

11 + 540779 = 540790
17 + 540773 = 540790
101 + 540689 = 540790
113 + 540677 = 540790
179 + 540611 = 540790
191 + 540599 = 540790
233 + 540557 = 540790
251 + 540539 = 540790

Showing the first eight; more decompositions exist.
