Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611376, here are decompositions:

47 + 31611329 = 31611376
53 + 31611323 = 31611376
239 + 31611137 = 31611376
263 + 31611113 = 31611376
347 + 31611029 = 31611376
353 + 31611023 = 31611376
359 + 31611017 = 31611376
509 + 31610867 = 31611376

Showing the first eight; more decompositions exist.
