Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592242, here are decompositions:

23 + 31592219 = 31592242
29 + 31592213 = 31592242
83 + 31592159 = 31592242
113 + 31592129 = 31592242
191 + 31592051 = 31592242
263 + 31591979 = 31592242
449 + 31591793 = 31592242
491 + 31591751 = 31592242

Showing the first eight; more decompositions exist.
