Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592342, here are decompositions:

31 + 31592311 = 31592342
139 + 31592203 = 31592342
181 + 31592161 = 31592342
193 + 31592149 = 31592342
349 + 31591993 = 31592342
433 + 31591909 = 31592342
499 + 31591843 = 31592342
619 + 31591723 = 31592342

Showing the first eight; more decompositions exist.
