Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468760, here are decompositions:

3 + 31468757 = 31468760
61 + 31468699 = 31468760
163 + 31468597 = 31468760
307 + 31468453 = 31468760
313 + 31468447 = 31468760
601 + 31468159 = 31468760
613 + 31468147 = 31468760
733 + 31468027 = 31468760

Showing the first eight; more decompositions exist.
