Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592454, here are decompositions:

7 + 31592447 = 31592454
17 + 31592437 = 31592454
31 + 31592423 = 31592454
37 + 31592417 = 31592454
43 + 31592411 = 31592454
97 + 31592357 = 31592454
107 + 31592347 = 31592454
163 + 31592291 = 31592454

Showing the first eight; more decompositions exist.
