Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526752, here are decompositions:

3 + 31526749 = 31526752
29 + 31526723 = 31526752
83 + 31526669 = 31526752
149 + 31526603 = 31526752
263 + 31526489 = 31526752
401 + 31526351 = 31526752
479 + 31526273 = 31526752
563 + 31526189 = 31526752

Showing the first eight; more decompositions exist.
