Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468964, here are decompositions:

61 + 31468903 = 31468964
103 + 31468861 = 31468964
367 + 31468597 = 31468964
421 + 31468543 = 31468964
733 + 31468231 = 31468964
937 + 31468027 = 31468964
997 + 31467967 = 31468964
1117 + 31467847 = 31468964

Showing the first eight; more decompositions exist.
