Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661742, here are decompositions:

53 + 8661689 = 8661742
59 + 8661683 = 8661742
101 + 8661641 = 8661742
113 + 8661629 = 8661742
233 + 8661509 = 8661742
251 + 8661491 = 8661742
263 + 8661479 = 8661742
281 + 8661461 = 8661742

Showing the first eight; more decompositions exist.
