Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562522, here are decompositions:

3 + 31562519 = 31562522
73 + 31562449 = 31562522
193 + 31562329 = 31562522
223 + 31562299 = 31562522
241 + 31562281 = 31562522
499 + 31562023 = 31562522
619 + 31561903 = 31562522
769 + 31561753 = 31562522

Showing the first eight; more decompositions exist.
