Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572062, here are decompositions:

3 + 31572059 = 31572062
13 + 31572049 = 31572062
79 + 31571983 = 31572062
163 + 31571899 = 31572062
229 + 31571833 = 31572062
241 + 31571821 = 31572062
283 + 31571779 = 31572062
331 + 31571731 = 31572062

Showing the first eight; more decompositions exist.
