Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588060, here are decompositions:

41 + 31588019 = 31588060
137 + 31587923 = 31588060
149 + 31587911 = 31588060
167 + 31587893 = 31588060
281 + 31587779 = 31588060
293 + 31587767 = 31588060
311 + 31587749 = 31588060
353 + 31587707 = 31588060

Showing the first eight; more decompositions exist.
