Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572674, here are decompositions:

37 + 31572637 = 31572674
103 + 31572571 = 31572674
151 + 31572523 = 31572674
163 + 31572511 = 31572674
271 + 31572403 = 31572674
373 + 31572301 = 31572674
421 + 31572253 = 31572674
433 + 31572241 = 31572674

Showing the first eight; more decompositions exist.
