Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 53440, here are decompositions:

3 + 53437 = 53440
29 + 53411 = 53440
59 + 53381 = 53440
113 + 53327 = 53440
131 + 53309 = 53440
173 + 53267 = 53440
239 + 53201 = 53440
251 + 53189 = 53440

Showing the first eight; more decompositions exist.
