Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469974, here are decompositions:

71 + 31469903 = 31469974
113 + 31469861 = 31469974
191 + 31469783 = 31469974
233 + 31469741 = 31469974
251 + 31469723 = 31469974
353 + 31469621 = 31469974
443 + 31469531 = 31469974
461 + 31469513 = 31469974

Showing the first eight; more decompositions exist.
