Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503052, here are decompositions:

59 + 31502993 = 31503052
89 + 31502963 = 31503052
353 + 31502699 = 31503052
491 + 31502561 = 31503052
563 + 31502489 = 31503052
569 + 31502483 = 31503052
593 + 31502459 = 31503052
719 + 31502333 = 31503052

Showing the first eight; more decompositions exist.
