Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740242, here are decompositions:

23 + 8740219 = 8740242
59 + 8740183 = 8740242
73 + 8740169 = 8740242
79 + 8740163 = 8740242
103 + 8740139 = 8740242
113 + 8740129 = 8740242
131 + 8740111 = 8740242
239 + 8740003 = 8740242

Showing the first eight; more decompositions exist.
