Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469944, here are decompositions:

41 + 31469903 = 31469944
83 + 31469861 = 31469944
131 + 31469813 = 31469944
383 + 31469561 = 31469944
431 + 31469513 = 31469944
503 + 31469441 = 31469944
521 + 31469423 = 31469944
557 + 31469387 = 31469944

Showing the first eight; more decompositions exist.
