Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592528, here are decompositions:

61 + 31592467 = 31592528
139 + 31592389 = 31592528
151 + 31592377 = 31592528
181 + 31592347 = 31592528
271 + 31592257 = 31592528
367 + 31592161 = 31592528
379 + 31592149 = 31592528
571 + 31591957 = 31592528

Showing the first eight; more decompositions exist.
