Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469802, here are decompositions:

5 + 31469797 = 31469802
19 + 31469783 = 31469802
41 + 31469761 = 31469802
61 + 31469741 = 31469802
71 + 31469731 = 31469802
79 + 31469723 = 31469802
113 + 31469689 = 31469802
131 + 31469671 = 31469802

Showing the first eight; more decompositions exist.
