Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503082, here are decompositions:

29 + 31503053 = 31503082
89 + 31502993 = 31503082
383 + 31502699 = 31503082
521 + 31502561 = 31503082
593 + 31502489 = 31503082
599 + 31502483 = 31503082
641 + 31502441 = 31503082
719 + 31502363 = 31503082

Showing the first eight; more decompositions exist.
