Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611608, here are decompositions:

31 + 31611577 = 31611608
151 + 31611457 = 31611608
229 + 31611379 = 31611608
241 + 31611367 = 31611608
307 + 31611301 = 31611608
337 + 31611271 = 31611608
421 + 31611187 = 31611608
541 + 31611067 = 31611608

Showing the first eight; more decompositions exist.
