Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476378, here are decompositions:

5 + 31476373 = 31476378
7 + 31476371 = 31476378
29 + 31476349 = 31476378
61 + 31476317 = 31476378
127 + 31476251 = 31476378
139 + 31476239 = 31476378
191 + 31476187 = 31476378
229 + 31476149 = 31476378

Showing the first eight; more decompositions exist.
