Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562592, here are decompositions:

41 + 31562551 = 31562592
73 + 31562519 = 31562592
109 + 31562483 = 31562592
151 + 31562441 = 31562592
163 + 31562429 = 31562592
263 + 31562329 = 31562592
293 + 31562299 = 31562592
311 + 31562281 = 31562592

Showing the first eight; more decompositions exist.
