Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 53840, here are decompositions:

67 + 53773 = 53840
109 + 53731 = 53840
211 + 53629 = 53840
223 + 53617 = 53840
229 + 53611 = 53840
271 + 53569 = 53840
313 + 53527 = 53840
337 + 53503 = 53840

Showing the first eight; more decompositions exist.
