Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506058, here are decompositions:

29 + 31506029 = 31506058
131 + 31505927 = 31506058
137 + 31505921 = 31506058
149 + 31505909 = 31506058
251 + 31505807 = 31506058
257 + 31505801 = 31506058
317 + 31505741 = 31506058
401 + 31505657 = 31506058

Showing the first eight; more decompositions exist.
