Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732222, here are decompositions:

13 + 8732209 = 8732222
151 + 8732071 = 8732222
193 + 8732029 = 8732222
199 + 8732023 = 8732222
229 + 8731993 = 8732222
241 + 8731981 = 8732222
271 + 8731951 = 8732222
283 + 8731939 = 8732222

Showing the first eight; more decompositions exist.
