Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485352, here are decompositions:

11 + 31485341 = 31485352
83 + 31485269 = 31485352
131 + 31485221 = 31485352
251 + 31485101 = 31485352
293 + 31485059 = 31485352
359 + 31484993 = 31485352
449 + 31484903 = 31485352
599 + 31484753 = 31485352

Showing the first eight; more decompositions exist.
