Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569010, here are decompositions:

41 + 31568969 = 31569010
71 + 31568939 = 31569010
89 + 31568921 = 31569010
101 + 31568909 = 31569010
113 + 31568897 = 31569010
131 + 31568879 = 31569010
167 + 31568843 = 31569010
353 + 31568657 = 31569010

Showing the first eight; more decompositions exist.
