Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592624, here are decompositions:

3 + 31592621 = 31592624
67 + 31592557 = 31592624
73 + 31592551 = 31592624
157 + 31592467 = 31592624
277 + 31592347 = 31592624
313 + 31592311 = 31592624
367 + 31592257 = 31592624
421 + 31592203 = 31592624

Showing the first eight; more decompositions exist.
