Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592894, here are decompositions:

61 + 31592833 = 31592894
97 + 31592797 = 31592894
211 + 31592683 = 31592894
337 + 31592557 = 31592894
457 + 31592437 = 31592894
547 + 31592347 = 31592894
691 + 31592203 = 31592894
733 + 31592161 = 31592894

Showing the first eight; more decompositions exist.
