Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611088, here are decompositions:

59 + 31611029 = 31611088
71 + 31611017 = 31611088
317 + 31610771 = 31611088
347 + 31610741 = 31611088
359 + 31610729 = 31611088
449 + 31610639 = 31611088
569 + 31610519 = 31611088
797 + 31610291 = 31611088

Showing the first eight; more decompositions exist.
