Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611544, here are decompositions:

5 + 31611539 = 31611544
17 + 31611527 = 31611544
71 + 31611473 = 31611544
233 + 31611311 = 31611544
431 + 31611113 = 31611544
443 + 31611101 = 31611544
521 + 31611023 = 31611544
677 + 31610867 = 31611544

Showing the first eight; more decompositions exist.
