Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520058, here are decompositions:

29 + 31520029 = 31520058
41 + 31520017 = 31520058
47 + 31520011 = 31520058
71 + 31519987 = 31520058
107 + 31519951 = 31520058
131 + 31519927 = 31520058
139 + 31519919 = 31520058
149 + 31519909 = 31520058

Showing the first eight; more decompositions exist.
