Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592026, here are decompositions:

29 + 31591997 = 31592026
47 + 31591979 = 31592026
113 + 31591913 = 31592026
233 + 31591793 = 31592026
293 + 31591733 = 31592026
359 + 31591667 = 31592026
449 + 31591577 = 31592026
509 + 31591517 = 31592026

Showing the first eight; more decompositions exist.
