Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592490, here are decompositions:

23 + 31592467 = 31592490
37 + 31592453 = 31592490
43 + 31592447 = 31592490
53 + 31592437 = 31592490
67 + 31592423 = 31592490
73 + 31592417 = 31592490
79 + 31592411 = 31592490
101 + 31592389 = 31592490

Showing the first eight; more decompositions exist.
