Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592498, here are decompositions:

31 + 31592467 = 31592498
61 + 31592437 = 31592498
109 + 31592389 = 31592498
151 + 31592347 = 31592498
241 + 31592257 = 31592498
337 + 31592161 = 31592498
349 + 31592149 = 31592498
499 + 31591999 = 31592498

Showing the first eight; more decompositions exist.
