Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572296, here are decompositions:

13 + 31572283 = 31572296
43 + 31572253 = 31572296
73 + 31572223 = 31572296
139 + 31572157 = 31572296
163 + 31572133 = 31572296
313 + 31571983 = 31572296
397 + 31571899 = 31572296
409 + 31571887 = 31572296

Showing the first eight; more decompositions exist.
