Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565346, here are decompositions:

23 + 31565323 = 31565346
37 + 31565309 = 31565346
47 + 31565299 = 31565346
53 + 31565293 = 31565346
67 + 31565279 = 31565346
89 + 31565257 = 31565346
97 + 31565249 = 31565346
139 + 31565207 = 31565346

Showing the first eight; more decompositions exist.
