Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713512, here are decompositions:

53 + 8713459 = 8713512
61 + 8713451 = 8713512
79 + 8713433 = 8713512
83 + 8713429 = 8713512
109 + 8713403 = 8713512
113 + 8713399 = 8713512
139 + 8713373 = 8713512
149 + 8713363 = 8713512

Showing the first eight; more decompositions exist.
