Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619142, here are decompositions:

11 + 8619131 = 8619142
41 + 8619101 = 8619142
71 + 8619071 = 8619142
83 + 8619059 = 8619142
89 + 8619053 = 8619142
101 + 8619041 = 8619142
263 + 8618879 = 8619142
281 + 8618861 = 8619142

Showing the first eight; more decompositions exist.
