Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704242, here are decompositions:

13 + 8704229 = 8704242
23 + 8704219 = 8704242
59 + 8704183 = 8704242
73 + 8704169 = 8704242
83 + 8704159 = 8704242
193 + 8704049 = 8704242
271 + 8703971 = 8704242
331 + 8703911 = 8704242

Showing the first eight; more decompositions exist.
