Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572336, here are decompositions:

13 + 31572323 = 31572336
53 + 31572283 = 31572336
73 + 31572263 = 31572336
83 + 31572253 = 31572336
109 + 31572227 = 31572336
113 + 31572223 = 31572336
179 + 31572157 = 31572336
193 + 31572143 = 31572336

Showing the first eight; more decompositions exist.
