Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 577640, here are decompositions:

3 + 577637 = 577640
13 + 577627 = 577640
67 + 577573 = 577640
103 + 577537 = 577640
109 + 577531 = 577640
127 + 577513 = 577640
157 + 577483 = 577640
241 + 577399 = 577640

Showing the first eight; more decompositions exist.
