Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669742, here are decompositions:

41 + 8669701 = 8669742
71 + 8669671 = 8669742
73 + 8669669 = 8669742
113 + 8669629 = 8669742
131 + 8669611 = 8669742
149 + 8669593 = 8669742
199 + 8669543 = 8669742
229 + 8669513 = 8669742

Showing the first eight; more decompositions exist.
