Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542260, here are decompositions:

31 + 31542229 = 31542260
97 + 31542163 = 31542260
157 + 31542103 = 31542260
193 + 31542067 = 31542260
223 + 31542037 = 31542260
229 + 31542031 = 31542260
271 + 31541989 = 31542260
283 + 31541977 = 31542260

Showing the first eight; more decompositions exist.
