Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712944, here are decompositions:

13 + 8712931 = 8712944
151 + 8712793 = 8712944
193 + 8712751 = 8712944
283 + 8712661 = 8712944
367 + 8712577 = 8712944
397 + 8712547 = 8712944
421 + 8712523 = 8712944
523 + 8712421 = 8712944

Showing the first eight; more decompositions exist.
