Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542230, here are decompositions:

67 + 31542163 = 31542230
127 + 31542103 = 31542230
163 + 31542067 = 31542230
193 + 31542037 = 31542230
199 + 31542031 = 31542230
229 + 31542001 = 31542230
241 + 31541989 = 31542230
331 + 31541899 = 31542230

Showing the first eight; more decompositions exist.
