Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488952, here are decompositions:

41 + 31488911 = 31488952
389 + 31488563 = 31488952
653 + 31488299 = 31488952
659 + 31488293 = 31488952
863 + 31488089 = 31488952
881 + 31488071 = 31488952
1289 + 31487663 = 31488952
1409 + 31487543 = 31488952

Showing the first eight; more decompositions exist.
