Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464100, here are decompositions:

53 + 31464047 = 31464100
137 + 31463963 = 31464100
179 + 31463921 = 31464100
191 + 31463909 = 31464100
251 + 31463849 = 31464100
257 + 31463843 = 31464100
293 + 31463807 = 31464100
383 + 31463717 = 31464100

Showing the first eight; more decompositions exist.
