Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637392, here are decompositions:

13 + 8637379 = 8637392
19 + 8637373 = 8637392
73 + 8637319 = 8637392
103 + 8637289 = 8637392
139 + 8637253 = 8637392
229 + 8637163 = 8637392
241 + 8637151 = 8637392
331 + 8637061 = 8637392

Showing the first eight; more decompositions exist.
