Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569052, here are decompositions:

3 + 31569049 = 31569052
83 + 31568969 = 31569052
113 + 31568939 = 31569052
131 + 31568921 = 31569052
173 + 31568879 = 31569052
491 + 31568561 = 31569052
509 + 31568543 = 31569052
653 + 31568399 = 31569052

Showing the first eight; more decompositions exist.
