Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737140, here are decompositions:

11 + 8737129 = 8737140
23 + 8737117 = 8737140
29 + 8737111 = 8737140
43 + 8737097 = 8737140
67 + 8737073 = 8737140
73 + 8737067 = 8737140
79 + 8737061 = 8737140
101 + 8737039 = 8737140

Showing the first eight; more decompositions exist.
