Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572326, here are decompositions:

3 + 31572323 = 31572326
43 + 31572283 = 31572326
73 + 31572253 = 31572326
103 + 31572223 = 31572326
193 + 31572133 = 31572326
277 + 31572049 = 31572326
439 + 31571887 = 31572326
523 + 31571803 = 31572326

Showing the first eight; more decompositions exist.
