Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469962, here are decompositions:

59 + 31469903 = 31469962
101 + 31469861 = 31469962
113 + 31469849 = 31469962
149 + 31469813 = 31469962
179 + 31469783 = 31469962
239 + 31469723 = 31469962
383 + 31469579 = 31469962
401 + 31469561 = 31469962

Showing the first eight; more decompositions exist.
