Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469488, here are decompositions:

41 + 31469447 = 31469488
47 + 31469441 = 31469488
101 + 31469387 = 31469488
131 + 31469357 = 31469488
311 + 31469177 = 31469488
419 + 31469069 = 31469488
461 + 31469027 = 31469488
521 + 31468967 = 31469488

Showing the first eight; more decompositions exist.
