Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572504, here are decompositions:

43 + 31572461 = 31572504
101 + 31572403 = 31572504
157 + 31572347 = 31572504
163 + 31572341 = 31572504
181 + 31572323 = 31572504
241 + 31572263 = 31572504
251 + 31572253 = 31572504
263 + 31572241 = 31572504

Showing the first eight; more decompositions exist.
