Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470734, here are decompositions:

13 + 31470721 = 31470734
73 + 31470661 = 31470734
397 + 31470337 = 31470734
541 + 31470193 = 31470734
661 + 31470073 = 31470734
811 + 31469923 = 31470734
877 + 31469857 = 31470734
937 + 31469797 = 31470734

Showing the first eight; more decompositions exist.
