Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592198, here are decompositions:

37 + 31592161 = 31592198
151 + 31592047 = 31592198
199 + 31591999 = 31592198
241 + 31591957 = 31592198
331 + 31591867 = 31592198
487 + 31591711 = 31592198
601 + 31591597 = 31592198
661 + 31591537 = 31592198

Showing the first eight; more decompositions exist.
