Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476544, here are decompositions:

83 + 31476461 = 31476544
107 + 31476437 = 31476544
131 + 31476413 = 31476544
173 + 31476371 = 31476544
191 + 31476353 = 31476544
227 + 31476317 = 31476544
293 + 31476251 = 31476544
401 + 31476143 = 31476544

Showing the first eight; more decompositions exist.
