Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737230, here are decompositions:

31 + 8737199 = 8737230
37 + 8737193 = 8737230
53 + 8737177 = 8737230
101 + 8737129 = 8737230
113 + 8737117 = 8737230
157 + 8737073 = 8737230
163 + 8737067 = 8737230
167 + 8737063 = 8737230

Showing the first eight; more decompositions exist.
