Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74440, here are decompositions:

29 + 74411 = 74440
59 + 74381 = 74440
83 + 74357 = 74440
239 + 74201 = 74440
251 + 74189 = 74440
263 + 74177 = 74440
281 + 74159 = 74440
347 + 74093 = 74440

Showing the first eight; more decompositions exist.
