Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562222, here are decompositions:

103 + 31562119 = 31562222
199 + 31562023 = 31562222
229 + 31561993 = 31562222
283 + 31561939 = 31562222
421 + 31561801 = 31562222
499 + 31561723 = 31562222
673 + 31561549 = 31562222
1051 + 31561171 = 31562222

Showing the first eight; more decompositions exist.
