Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468892, here are decompositions:

31 + 31468861 = 31468892
43 + 31468849 = 31468892
193 + 31468699 = 31468892
349 + 31468543 = 31468892
421 + 31468471 = 31468892
439 + 31468453 = 31468892
523 + 31468369 = 31468892
661 + 31468231 = 31468892

Showing the first eight; more decompositions exist.
