Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543098, here are decompositions:

19 + 31543079 = 31543098
29 + 31543069 = 31543098
31 + 31543067 = 31543098
79 + 31543019 = 31543098
89 + 31543009 = 31543098
107 + 31542991 = 31543098
127 + 31542971 = 31543098
131 + 31542967 = 31543098

Showing the first eight; more decompositions exist.
