Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731226, here are decompositions:

13 + 8731213 = 8731226
73 + 8731153 = 8731226
157 + 8731069 = 8731226
199 + 8731027 = 8731226
277 + 8730949 = 8731226
307 + 8730919 = 8731226
313 + 8730913 = 8731226
337 + 8730889 = 8731226

Showing the first eight; more decompositions exist.
