Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474500, here are decompositions:

11 + 31474489 = 31474500
19 + 31474481 = 31474500
67 + 31474433 = 31474500
97 + 31474403 = 31474500
103 + 31474397 = 31474500
137 + 31474363 = 31474500
149 + 31474351 = 31474500
157 + 31474343 = 31474500

Showing the first eight; more decompositions exist.
