Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489036, here are decompositions:

239 + 31488797 = 31489036
269 + 31488767 = 31489036
389 + 31488647 = 31489036
479 + 31488557 = 31489036
743 + 31488293 = 31489036
809 + 31488227 = 31489036
947 + 31488089 = 31489036
977 + 31488059 = 31489036

Showing the first eight; more decompositions exist.
