Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725168, here are decompositions:

29 + 8725139 = 8725168
131 + 8725037 = 8725168
239 + 8724929 = 8725168
449 + 8724719 = 8725168
701 + 8724467 = 8725168
797 + 8724371 = 8725168
821 + 8724347 = 8725168
839 + 8724329 = 8725168

Showing the first eight; more decompositions exist.
