Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737278, here are decompositions:

7 + 8737271 = 8737278
29 + 8737249 = 8737278
31 + 8737247 = 8737278
41 + 8737237 = 8737278
79 + 8737199 = 8737278
101 + 8737177 = 8737278
139 + 8737139 = 8737278
149 + 8737129 = 8737278

Showing the first eight; more decompositions exist.
