Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476088, here are decompositions:

29 + 31476059 = 31476088
71 + 31476017 = 31476088
179 + 31475909 = 31476088
239 + 31475849 = 31476088
311 + 31475777 = 31476088
317 + 31475771 = 31476088
419 + 31475669 = 31476088
491 + 31475597 = 31476088

Showing the first eight; more decompositions exist.
