Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592444, here are decompositions:

7 + 31592437 = 31592444
67 + 31592377 = 31592444
97 + 31592347 = 31592444
241 + 31592203 = 31592444
271 + 31592173 = 31592444
283 + 31592161 = 31592444
397 + 31592047 = 31592444
487 + 31591957 = 31592444

Showing the first eight; more decompositions exist.
