Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592520, here are decompositions:

31 + 31592489 = 31592520
53 + 31592467 = 31592520
67 + 31592453 = 31592520
73 + 31592447 = 31592520
83 + 31592437 = 31592520
97 + 31592423 = 31592520
103 + 31592417 = 31592520
109 + 31592411 = 31592520

Showing the first eight; more decompositions exist.
