Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564374, here are decompositions:

13 + 31564361 = 31564374
41 + 31564333 = 31564374
43 + 31564331 = 31564374
47 + 31564327 = 31564374
53 + 31564321 = 31564374
103 + 31564271 = 31564374
113 + 31564261 = 31564374
131 + 31564243 = 31564374

Showing the first eight; more decompositions exist.
