Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469702, here are decompositions:

13 + 31469689 = 31469702
31 + 31469671 = 31469702
73 + 31469629 = 31469702
79 + 31469623 = 31469702
139 + 31469563 = 31469702
349 + 31469353 = 31469702
379 + 31469323 = 31469702
409 + 31469293 = 31469702

Showing the first eight; more decompositions exist.
