Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562024, here are decompositions:

7 + 31562017 = 31562024
31 + 31561993 = 31562024
97 + 31561927 = 31562024
223 + 31561801 = 31562024
271 + 31561753 = 31562024
313 + 31561711 = 31562024
331 + 31561693 = 31562024
601 + 31561423 = 31562024

Showing the first eight; more decompositions exist.
