Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74156, here are decompositions:

7 + 74149 = 74156
13 + 74143 = 74156
79 + 74077 = 74156
109 + 74047 = 74156
139 + 74017 = 74156
157 + 73999 = 74156
307 + 73849 = 74156
337 + 73819 = 74156

Showing the first eight; more decompositions exist.
