Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725740, here are decompositions:

7 + 8725733 = 8725740
41 + 8725699 = 8725740
59 + 8725681 = 8725740
71 + 8725669 = 8725740
83 + 8725657 = 8725740
97 + 8725643 = 8725740
109 + 8725631 = 8725740
113 + 8725627 = 8725740

Showing the first eight; more decompositions exist.
