Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488052, here are decompositions:

59 + 31487993 = 31488052
179 + 31487873 = 31488052
269 + 31487783 = 31488052
389 + 31487663 = 31488052
443 + 31487609 = 31488052
509 + 31487543 = 31488052
641 + 31487411 = 31488052
683 + 31487369 = 31488052

Showing the first eight; more decompositions exist.
