Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592272, here are decompositions:

53 + 31592219 = 31592272
59 + 31592213 = 31592272
113 + 31592159 = 31592272
149 + 31592123 = 31592272
233 + 31592039 = 31592272
293 + 31591979 = 31592272
359 + 31591913 = 31592272
479 + 31591793 = 31592272

Showing the first eight; more decompositions exist.
