Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503022, here are decompositions:

29 + 31502993 = 31503022
59 + 31502963 = 31503022
461 + 31502561 = 31503022
563 + 31502459 = 31503022
659 + 31502363 = 31503022
743 + 31502279 = 31503022
809 + 31502213 = 31503022
839 + 31502183 = 31503022

Showing the first eight; more decompositions exist.
