Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532222, here are decompositions:

3 + 31532219 = 31532222
13 + 31532209 = 31532222
19 + 31532203 = 31532222
109 + 31532113 = 31532222
151 + 31532071 = 31532222
313 + 31531909 = 31532222
409 + 31531813 = 31532222
643 + 31531579 = 31532222

Showing the first eight; more decompositions exist.
