Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564862, here are decompositions:

13 + 31564849 = 31564862
31 + 31564831 = 31564862
139 + 31564723 = 31564862
193 + 31564669 = 31564862
223 + 31564639 = 31564862
271 + 31564591 = 31564862
331 + 31564531 = 31564862
541 + 31564321 = 31564862

Showing the first eight; more decompositions exist.
