Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468904, here are decompositions:

3 + 31468901 = 31468904
43 + 31468861 = 31468904
127 + 31468777 = 31468904
307 + 31468597 = 31468904
331 + 31468573 = 31468904
433 + 31468471 = 31468904
457 + 31468447 = 31468904
661 + 31468243 = 31468904

Showing the first eight; more decompositions exist.
