Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592252, here are decompositions:

79 + 31592173 = 31592252
103 + 31592149 = 31592252
199 + 31592053 = 31592252
379 + 31591873 = 31592252
409 + 31591843 = 31592252
541 + 31591711 = 31592252
739 + 31591513 = 31592252
1093 + 31591159 = 31592252

Showing the first eight; more decompositions exist.
