Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739982, here are decompositions:

29 + 8739953 = 8739982
71 + 8739911 = 8739982
113 + 8739869 = 8739982
131 + 8739851 = 8739982
179 + 8739803 = 8739982
233 + 8739749 = 8739982
269 + 8739713 = 8739982
311 + 8739671 = 8739982

Showing the first eight; more decompositions exist.
