Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592020, here are decompositions:

23 + 31591997 = 31592020
41 + 31591979 = 31592020
107 + 31591913 = 31592020
227 + 31591793 = 31592020
269 + 31591751 = 31592020
281 + 31591739 = 31592020
353 + 31591667 = 31592020
419 + 31591601 = 31592020

Showing the first eight; more decompositions exist.
