Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542276, here are decompositions:

43 + 31542233 = 31542276
47 + 31542229 = 31542276
79 + 31542197 = 31542276
113 + 31542163 = 31542276
127 + 31542149 = 31542276
163 + 31542113 = 31542276
173 + 31542103 = 31542276
193 + 31542083 = 31542276

Showing the first eight; more decompositions exist.
