Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712844, here are decompositions:

17 + 8712827 = 8712844
83 + 8712761 = 8712844
131 + 8712713 = 8712844
167 + 8712677 = 8712844
233 + 8712611 = 8712844
311 + 8712533 = 8712844
347 + 8712497 = 8712844
353 + 8712491 = 8712844

Showing the first eight; more decompositions exist.
