Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469002, here are decompositions:

83 + 31468919 = 31469002
101 + 31468901 = 31469002
179 + 31468823 = 31469002
431 + 31468571 = 31469002
443 + 31468559 = 31469002
449 + 31468553 = 31469002
479 + 31468523 = 31469002
491 + 31468511 = 31469002

Showing the first eight; more decompositions exist.
