Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737240, here are decompositions:

3 + 8737237 = 8737240
41 + 8737199 = 8737240
47 + 8737193 = 8737240
101 + 8737139 = 8737240
167 + 8737073 = 8737240
173 + 8737067 = 8737240
179 + 8737061 = 8737240
191 + 8737049 = 8737240

Showing the first eight; more decompositions exist.
