Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540804, here are decompositions:

23 + 540781 = 540804
31 + 540773 = 540804
53 + 540751 = 540804
101 + 540703 = 540804
107 + 540697 = 540804
113 + 540691 = 540804
127 + 540677 = 540804
191 + 540613 = 540804

Showing the first eight; more decompositions exist.
