Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737940, here are decompositions:

7 + 8737933 = 8737940
19 + 8737921 = 8737940
67 + 8737873 = 8737940
73 + 8737867 = 8737940
97 + 8737843 = 8737940
139 + 8737801 = 8737940
151 + 8737789 = 8737940
157 + 8737783 = 8737940

Showing the first eight; more decompositions exist.
