Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011222, here are decompositions:

5 + 1011217 = 1011222
31 + 1011191 = 1011222
59 + 1011163 = 1011222
83 + 1011139 = 1011222
131 + 1011091 = 1011222
151 + 1011071 = 1011222
193 + 1011029 = 1011222
229 + 1010993 = 1011222

Showing the first eight; more decompositions exist.
