Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469862, here are decompositions:

5 + 31469857 = 31469862
13 + 31469849 = 31469862
79 + 31469783 = 31469862
101 + 31469761 = 31469862
131 + 31469731 = 31469862
139 + 31469723 = 31469862
173 + 31469689 = 31469862
191 + 31469671 = 31469862

Showing the first eight; more decompositions exist.
