Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562792, here are decompositions:

13 + 31562779 = 31562792
109 + 31562683 = 31562792
181 + 31562611 = 31562792
199 + 31562593 = 31562792
241 + 31562551 = 31562792
463 + 31562329 = 31562792
673 + 31562119 = 31562792
739 + 31562053 = 31562792

Showing the first eight; more decompositions exist.
