Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468634, here are decompositions:

3 + 31468631 = 31468634
37 + 31468597 = 31468634
61 + 31468573 = 31468634
163 + 31468471 = 31468634
181 + 31468453 = 31468634
433 + 31468201 = 31468634
487 + 31468147 = 31468634
607 + 31468027 = 31468634

Showing the first eight; more decompositions exist.
