Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750840, here are decompositions:

31 + 8750809 = 8750840
79 + 8750761 = 8750840
103 + 8750737 = 8750840
127 + 8750713 = 8750840
139 + 8750701 = 8750840
151 + 8750689 = 8750840
199 + 8750641 = 8750840
313 + 8750527 = 8750840

Showing the first eight; more decompositions exist.
