Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737180, here are decompositions:

3 + 8737177 = 8737180
41 + 8737139 = 8737180
83 + 8737097 = 8737180
107 + 8737073 = 8737180
113 + 8737067 = 8737180
131 + 8737049 = 8737180
191 + 8736989 = 8737180
269 + 8736911 = 8737180

Showing the first eight; more decompositions exist.
