Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977222, here are decompositions:

13 + 977209 = 977222
19 + 977203 = 977222
31 + 977191 = 977222
73 + 977149 = 977222
199 + 977023 = 977222
271 + 976951 = 977222
313 + 976909 = 977222
373 + 976849 = 977222

Showing the first eight; more decompositions exist.
