Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719208, here are decompositions:

31 + 8719177 = 8719208
67 + 8719141 = 8719208
109 + 8719099 = 8719208
151 + 8719057 = 8719208
331 + 8718877 = 8719208
349 + 8718859 = 8719208
397 + 8718811 = 8719208
409 + 8718799 = 8719208

Showing the first eight; more decompositions exist.
