Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564354, here are decompositions:

23 + 31564331 = 31564354
83 + 31564271 = 31564354
113 + 31564241 = 31564354
191 + 31564163 = 31564354
197 + 31564157 = 31564354
251 + 31564103 = 31564354
401 + 31563953 = 31564354
443 + 31563911 = 31564354

Showing the first eight; more decompositions exist.
