Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 543640, here are decompositions:

3 + 543637 = 543640
23 + 543617 = 543640
29 + 543611 = 543640
47 + 543593 = 543640
89 + 543551 = 543640
101 + 543539 = 543640
131 + 543509 = 543640
137 + 543503 = 543640

Showing the first eight; more decompositions exist.
