Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620242, here are decompositions:

11 + 8620231 = 8620242
23 + 8620219 = 8620242
31 + 8620211 = 8620242
53 + 8620189 = 8620242
83 + 8620159 = 8620242
101 + 8620141 = 8620242
109 + 8620133 = 8620242
131 + 8620111 = 8620242

Showing the first eight; more decompositions exist.
