Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737290, here are decompositions:

13 + 8737277 = 8737290
19 + 8737271 = 8737290
41 + 8737249 = 8737290
43 + 8737247 = 8737290
47 + 8737243 = 8737290
53 + 8737237 = 8737290
97 + 8737193 = 8737290
113 + 8737177 = 8737290

Showing the first eight; more decompositions exist.
