Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591684, here are decompositions:

61 + 8591623 = 8591684
67 + 8591617 = 8591684
97 + 8591587 = 8591684
151 + 8591533 = 8591684
307 + 8591377 = 8591684
373 + 8591311 = 8591684
433 + 8591251 = 8591684
457 + 8591227 = 8591684

Showing the first eight; more decompositions exist.
