Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649162, here are decompositions:

59 + 8649103 = 8649162
83 + 8649079 = 8649162
101 + 8649061 = 8649162
113 + 8649049 = 8649162
139 + 8649023 = 8649162
233 + 8648929 = 8649162
239 + 8648923 = 8649162
241 + 8648921 = 8649162

Showing the first eight; more decompositions exist.
