Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611418, here are decompositions:

89 + 31611329 = 31611418
107 + 31611311 = 31611418
281 + 31611137 = 31611418
317 + 31611101 = 31611418
389 + 31611029 = 31611418
401 + 31611017 = 31611418
647 + 31610771 = 31611418
677 + 31610741 = 31611418

Showing the first eight; more decompositions exist.
