Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469012, here are decompositions:

19 + 31468993 = 31469012
109 + 31468903 = 31469012
151 + 31468861 = 31469012
163 + 31468849 = 31469012
313 + 31468699 = 31469012
439 + 31468573 = 31469012
541 + 31468471 = 31469012
613 + 31468399 = 31469012

Showing the first eight; more decompositions exist.
