Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31487176, here are decompositions:

5 + 31487171 = 31487176
23 + 31487153 = 31487176
29 + 31487147 = 31487176
89 + 31487087 = 31487176
113 + 31487063 = 31487176
317 + 31486859 = 31487176
443 + 31486733 = 31487176
449 + 31486727 = 31487176

Showing the first eight; more decompositions exist.
