Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592222, here are decompositions:

3 + 31592219 = 31592222
19 + 31592203 = 31592222
61 + 31592161 = 31592222
73 + 31592149 = 31592222
223 + 31591999 = 31592222
229 + 31591993 = 31592222
313 + 31591909 = 31592222
349 + 31591873 = 31592222

Showing the first eight; more decompositions exist.
