Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 464440, here are decompositions:

3 + 464437 = 464440
59 + 464381 = 464440
89 + 464351 = 464440
113 + 464327 = 464440
131 + 464309 = 464440
149 + 464291 = 464440
227 + 464213 = 464440
239 + 464201 = 464440

Showing the first eight; more decompositions exist.
