Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468532, here are decompositions:

3 + 31468529 = 31468532
61 + 31468471 = 31468532
79 + 31468453 = 31468532
163 + 31468369 = 31468532
331 + 31468201 = 31468532
373 + 31468159 = 31468532
769 + 31467763 = 31468532
811 + 31467721 = 31468532

Showing the first eight; more decompositions exist.
