Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468232, here are decompositions:

31 + 31468201 = 31468232
73 + 31468159 = 31468232
283 + 31467949 = 31468232
379 + 31467853 = 31468232
421 + 31467811 = 31468232
541 + 31467691 = 31468232
643 + 31467589 = 31468232
661 + 31467571 = 31468232

Showing the first eight; more decompositions exist.
