Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731222, here are decompositions:

11 + 8731211 = 8731222
83 + 8731139 = 8731222
113 + 8731109 = 8731222
191 + 8731031 = 8731222
239 + 8730983 = 8731222
293 + 8730929 = 8731222
359 + 8730863 = 8731222
419 + 8730803 = 8731222

Showing the first eight; more decompositions exist.
