Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726312, here are decompositions:

73 + 8726239 = 8726312
103 + 8726209 = 8726312
109 + 8726203 = 8726312
211 + 8726101 = 8726312
313 + 8725999 = 8726312
349 + 8725963 = 8726312
499 + 8725813 = 8726312
613 + 8725699 = 8726312

Showing the first eight; more decompositions exist.
