Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74220, here are decompositions:

11 + 74209 = 74220
17 + 74203 = 74220
19 + 74201 = 74220
23 + 74197 = 74220
31 + 74189 = 74220
43 + 74177 = 74220
53 + 74167 = 74220
59 + 74161 = 74220

Showing the first eight; more decompositions exist.
