Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503764, here are decompositions:

13 + 31503751 = 31503764
31 + 31503733 = 31503764
37 + 31503727 = 31503764
211 + 31503553 = 31503764
421 + 31503343 = 31503764
433 + 31503331 = 31503764
547 + 31503217 = 31503764
613 + 31503151 = 31503764

Showing the first eight; more decompositions exist.
