Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611346, here are decompositions:

5 + 31611341 = 31611346
17 + 31611329 = 31611346
23 + 31611323 = 31611346
47 + 31611299 = 31611346
233 + 31611113 = 31611346
257 + 31611089 = 31611346
317 + 31611029 = 31611346
479 + 31610867 = 31611346

Showing the first eight; more decompositions exist.
