Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592140, here are decompositions:

11 + 31592129 = 31592140
17 + 31592123 = 31592140
89 + 31592051 = 31592140
101 + 31592039 = 31592140
227 + 31591913 = 31592140
347 + 31591793 = 31592140
389 + 31591751 = 31592140
401 + 31591739 = 31592140

Showing the first eight; more decompositions exist.
