Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720118, here are decompositions:

5 + 8720113 = 8720118
7 + 8720111 = 8720118
31 + 8720087 = 8720118
37 + 8720081 = 8720118
47 + 8720071 = 8720118
61 + 8720057 = 8720118
131 + 8719987 = 8720118
157 + 8719961 = 8720118

Showing the first eight; more decompositions exist.
