Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567010, here are decompositions:

31 + 31566979 = 31567010
37 + 31566973 = 31567010
43 + 31566967 = 31567010
109 + 31566901 = 31567010
193 + 31566817 = 31567010
379 + 31566631 = 31567010
421 + 31566589 = 31567010
463 + 31566547 = 31567010

Showing the first eight; more decompositions exist.
