Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543106, here are decompositions:

3 + 31543103 = 31543106
37 + 31543069 = 31543106
97 + 31543009 = 31543106
139 + 31542967 = 31543106
157 + 31542949 = 31543106
163 + 31542943 = 31543106
229 + 31542877 = 31543106
277 + 31542829 = 31543106

Showing the first eight; more decompositions exist.
