Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476400, here are decompositions:

17 + 31476383 = 31476400
29 + 31476371 = 31476400
47 + 31476353 = 31476400
83 + 31476317 = 31476400
149 + 31476251 = 31476400
251 + 31476149 = 31476400
257 + 31476143 = 31476400
281 + 31476119 = 31476400

Showing the first eight; more decompositions exist.
