Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592204, here are decompositions:

31 + 31592173 = 31592204
43 + 31592161 = 31592204
151 + 31592053 = 31592204
157 + 31592047 = 31592204
211 + 31591993 = 31592204
331 + 31591873 = 31592204
337 + 31591867 = 31592204
367 + 31591837 = 31592204

Showing the first eight; more decompositions exist.
