Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707242, here are decompositions:

23 + 8707219 = 8707242
53 + 8707189 = 8707242
59 + 8707183 = 8707242
83 + 8707159 = 8707242
139 + 8707103 = 8707242
149 + 8707093 = 8707242
151 + 8707091 = 8707242
211 + 8707031 = 8707242

Showing the first eight; more decompositions exist.
