Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570750, here are decompositions:

41 + 31570709 = 31570750
83 + 31570667 = 31570750
131 + 31570619 = 31570750
137 + 31570613 = 31570750
173 + 31570577 = 31570750
251 + 31570499 = 31570750
269 + 31570481 = 31570750
353 + 31570397 = 31570750

Showing the first eight; more decompositions exist.
