Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456058, here are decompositions:

37 + 31456021 = 31456058
97 + 31455961 = 31456058
157 + 31455901 = 31456058
181 + 31455877 = 31456058
199 + 31455859 = 31456058
229 + 31455829 = 31456058
307 + 31455751 = 31456058
331 + 31455727 = 31456058

Showing the first eight; more decompositions exist.
