Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592186, here are decompositions:

13 + 31592173 = 31592186
37 + 31592149 = 31592186
139 + 31592047 = 31592186
193 + 31591993 = 31592186
229 + 31591957 = 31592186
277 + 31591909 = 31592186
313 + 31591873 = 31592186
349 + 31591837 = 31592186

Showing the first eight; more decompositions exist.
