Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622142, here are decompositions:

5 + 8622137 = 8622142
29 + 8622113 = 8622142
71 + 8622071 = 8622142
101 + 8622041 = 8622142
131 + 8622011 = 8622142
281 + 8621861 = 8622142
311 + 8621831 = 8622142
449 + 8621693 = 8622142

Showing the first eight; more decompositions exist.
