Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 58640, here are decompositions:

37 + 58603 = 58640
61 + 58579 = 58640
67 + 58573 = 58640
73 + 58567 = 58640
97 + 58543 = 58640
103 + 58537 = 58640
163 + 58477 = 58640
199 + 58441 = 58640

Showing the first eight; more decompositions exist.
