Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737320, here are decompositions:

19 + 8737301 = 8737320
43 + 8737277 = 8737320
71 + 8737249 = 8737320
73 + 8737247 = 8737320
83 + 8737237 = 8737320
127 + 8737193 = 8737320
167 + 8737153 = 8737320
181 + 8737139 = 8737320

Showing the first eight; more decompositions exist.
