Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592258, here are decompositions:

97 + 31592161 = 31592258
109 + 31592149 = 31592258
211 + 31592047 = 31592258
349 + 31591909 = 31592258
421 + 31591837 = 31592258
547 + 31591711 = 31592258
571 + 31591687 = 31592258
661 + 31591597 = 31592258

Showing the first eight; more decompositions exist.
