Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564484, here are decompositions:

37 + 31564447 = 31564484
97 + 31564387 = 31564484
151 + 31564333 = 31564484
157 + 31564327 = 31564484
163 + 31564321 = 31564484
223 + 31564261 = 31564484
241 + 31564243 = 31564484
277 + 31564207 = 31564484

Showing the first eight; more decompositions exist.
