Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562312, here are decompositions:

13 + 31562299 = 31562312
31 + 31562281 = 31562312
193 + 31562119 = 31562312
373 + 31561939 = 31562312
409 + 31561903 = 31562312
601 + 31561711 = 31562312
619 + 31561693 = 31562312
643 + 31561669 = 31562312

Showing the first eight; more decompositions exist.
