Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469850, here are decompositions:

37 + 31469813 = 31469850
53 + 31469797 = 31469850
67 + 31469783 = 31469850
89 + 31469761 = 31469850
109 + 31469741 = 31469850
127 + 31469723 = 31469850
179 + 31469671 = 31469850
197 + 31469653 = 31469850

Showing the first eight; more decompositions exist.
