Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579622, here are decompositions:

3 + 31579619 = 31579622
79 + 31579543 = 31579622
103 + 31579519 = 31579622
211 + 31579411 = 31579622
223 + 31579399 = 31579622
229 + 31579393 = 31579622
271 + 31579351 = 31579622
331 + 31579291 = 31579622

Showing the first eight; more decompositions exist.
