Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580348, here are decompositions:

31 + 31580317 = 31580348
109 + 31580239 = 31580348
127 + 31580221 = 31580348
199 + 31580149 = 31580348
229 + 31580119 = 31580348
271 + 31580077 = 31580348
379 + 31579969 = 31580348
439 + 31579909 = 31580348

Showing the first eight; more decompositions exist.
