Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76578, here are decompositions:

17 + 76561 = 76578
37 + 76541 = 76578
41 + 76537 = 76578
59 + 76519 = 76578
67 + 76511 = 76578
71 + 76507 = 76578
97 + 76481 = 76578
107 + 76471 = 76578

Showing the first eight; more decompositions exist.
