Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704072, here are decompositions:

5 + 8704067 = 8704072
23 + 8704049 = 8704072
101 + 8703971 = 8704072
173 + 8703899 = 8704072
239 + 8703833 = 8704072
353 + 8703719 = 8704072
431 + 8703641 = 8704072
449 + 8703623 = 8704072

Showing the first eight; more decompositions exist.
