Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464558, here are decompositions:

11 + 31464547 = 31464558
107 + 31464451 = 31464558
131 + 31464427 = 31464558
137 + 31464421 = 31464558
149 + 31464409 = 31464558
157 + 31464401 = 31464558
199 + 31464359 = 31464558
277 + 31464281 = 31464558

Showing the first eight; more decompositions exist.
