Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572524, here are decompositions:

3 + 31572521 = 31572524
13 + 31572511 = 31572524
223 + 31572301 = 31572524
241 + 31572283 = 31572524
271 + 31572253 = 31572524
283 + 31572241 = 31572524
367 + 31572157 = 31572524
541 + 31571983 = 31572524

Showing the first eight; more decompositions exist.
