Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527152, here are decompositions:

3 + 31527149 = 31527152
43 + 31527109 = 31527152
199 + 31526953 = 31527152
211 + 31526941 = 31527152
271 + 31526881 = 31527152
379 + 31526773 = 31527152
421 + 31526731 = 31527152
439 + 31526713 = 31527152

Showing the first eight; more decompositions exist.
