Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712512, here are decompositions:

139 + 8712373 = 8712512
163 + 8712349 = 8712512
283 + 8712229 = 8712512
331 + 8712181 = 8712512
349 + 8712163 = 8712512
379 + 8712133 = 8712512
421 + 8712091 = 8712512
541 + 8711971 = 8712512

Showing the first eight; more decompositions exist.
