Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74180, here are decompositions:

3 + 74177 = 74180
13 + 74167 = 74180
19 + 74161 = 74180
31 + 74149 = 74180
37 + 74143 = 74180
79 + 74101 = 74180
103 + 74077 = 74180
109 + 74071 = 74180

Showing the first eight; more decompositions exist.
