Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611434, here are decompositions:

31 + 31611403 = 31611434
67 + 31611367 = 31611434
163 + 31611271 = 31611434
271 + 31611163 = 31611434
307 + 31611127 = 31611434
367 + 31611067 = 31611434
397 + 31611037 = 31611434
523 + 31610911 = 31611434

Showing the first eight; more decompositions exist.
