Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476288, here are decompositions:

5 + 31476283 = 31476288
37 + 31476251 = 31476288
101 + 31476187 = 31476288
131 + 31476157 = 31476288
139 + 31476149 = 31476288
191 + 31476097 = 31476288
229 + 31476059 = 31476288
257 + 31476031 = 31476288

Showing the first eight; more decompositions exist.
