Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564392, here are decompositions:

5 + 31564387 = 31564392
31 + 31564361 = 31564392
59 + 31564333 = 31564392
61 + 31564331 = 31564392
71 + 31564321 = 31564392
131 + 31564261 = 31564392
149 + 31564243 = 31564392
151 + 31564241 = 31564392

Showing the first eight; more decompositions exist.
