Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543058, here are decompositions:

67 + 31542991 = 31543058
109 + 31542949 = 31543058
181 + 31542877 = 31543058
229 + 31542829 = 31543058
271 + 31542787 = 31543058
331 + 31542727 = 31543058
499 + 31542559 = 31543058
571 + 31542487 = 31543058

Showing the first eight; more decompositions exist.
