Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448058, here are decompositions:

41 + 31448017 = 31448058
71 + 31447987 = 31448058
97 + 31447961 = 31448058
101 + 31447957 = 31448058
107 + 31447951 = 31448058
127 + 31447931 = 31448058
157 + 31447901 = 31448058
307 + 31447751 = 31448058

Showing the first eight; more decompositions exist.
