Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540698, here are decompositions:

7 + 540691 = 540698
19 + 540679 = 540698
79 + 540619 = 540698
139 + 540559 = 540698
157 + 540541 = 540698
181 + 540517 = 540698
229 + 540469 = 540698
307 + 540391 = 540698

Showing the first eight; more decompositions exist.
