Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572704, here are decompositions:

67 + 31572637 = 31572704
181 + 31572523 = 31572704
193 + 31572511 = 31572704
421 + 31572283 = 31572704
463 + 31572241 = 31572704
523 + 31572181 = 31572704
547 + 31572157 = 31572704
571 + 31572133 = 31572704

Showing the first eight; more decompositions exist.
