Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592372, here are decompositions:

3 + 31592369 = 31592372
61 + 31592311 = 31592372
199 + 31592173 = 31592372
211 + 31592161 = 31592372
223 + 31592149 = 31592372
373 + 31591999 = 31592372
379 + 31591993 = 31592372
463 + 31591909 = 31592372

Showing the first eight; more decompositions exist.
