Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40424, here are decompositions:

37 + 40387 = 40424
67 + 40357 = 40424
73 + 40351 = 40424
193 + 40231 = 40424
211 + 40213 = 40424
271 + 40153 = 40424
313 + 40111 = 40424
331 + 40093 = 40424

Showing the first eight; more decompositions exist.
