Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469954, here are decompositions:

31 + 31469923 = 31469954
97 + 31469857 = 31469954
157 + 31469797 = 31469954
193 + 31469761 = 31469954
223 + 31469731 = 31469954
283 + 31469671 = 31469954
331 + 31469623 = 31469954
367 + 31469587 = 31469954

Showing the first eight; more decompositions exist.
