Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469894, here are decompositions:

37 + 31469857 = 31469894
97 + 31469797 = 31469894
163 + 31469731 = 31469894
223 + 31469671 = 31469894
241 + 31469653 = 31469894
271 + 31469623 = 31469894
307 + 31469587 = 31469894
331 + 31469563 = 31469894

Showing the first eight; more decompositions exist.
