Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505058, here are decompositions:

19 + 31505039 = 31505058
31 + 31505027 = 31505058
59 + 31504999 = 31505058
71 + 31504987 = 31505058
107 + 31504951 = 31505058
149 + 31504909 = 31505058
239 + 31504819 = 31505058
257 + 31504801 = 31505058

Showing the first eight; more decompositions exist.
