Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469776, here are decompositions:

53 + 31469723 = 31469776
197 + 31469579 = 31469776
257 + 31469519 = 31469776
263 + 31469513 = 31469776
353 + 31469423 = 31469776
389 + 31469387 = 31469776
419 + 31469357 = 31469776
449 + 31469327 = 31469776

Showing the first eight; more decompositions exist.
