Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572652, here are decompositions:

3 + 31572649 = 31572652
5 + 31572647 = 31572652
11 + 31572641 = 31572652
101 + 31572551 = 31572652
131 + 31572521 = 31572652
191 + 31572461 = 31572652
239 + 31572413 = 31572652
263 + 31572389 = 31572652

Showing the first eight; more decompositions exist.
