Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740858, here are decompositions:

17 + 8740841 = 8740858
59 + 8740799 = 8740858
101 + 8740757 = 8740858
131 + 8740727 = 8740858
179 + 8740679 = 8740858
251 + 8740607 = 8740858
281 + 8740577 = 8740858
317 + 8740541 = 8740858

Showing the first eight; more decompositions exist.
