Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572214, here are decompositions:

53 + 31572161 = 31572214
71 + 31572143 = 31572214
83 + 31572131 = 31572214
131 + 31572083 = 31572214
173 + 31572041 = 31572214
197 + 31572017 = 31572214
251 + 31571963 = 31572214
257 + 31571957 = 31572214

Showing the first eight; more decompositions exist.
