Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592234, here are decompositions:

31 + 31592203 = 31592234
61 + 31592173 = 31592234
73 + 31592161 = 31592234
181 + 31592053 = 31592234
241 + 31591993 = 31592234
277 + 31591957 = 31592234
367 + 31591867 = 31592234
397 + 31591837 = 31592234

Showing the first eight; more decompositions exist.
