Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624242, here are decompositions:

5 + 8624237 = 8624242
41 + 8624201 = 8624242
59 + 8624183 = 8624242
83 + 8624159 = 8624242
89 + 8624153 = 8624242
101 + 8624141 = 8624242
113 + 8624129 = 8624242
131 + 8624111 = 8624242

Showing the first eight; more decompositions exist.
