Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72174, here are decompositions:

5 + 72169 = 72174
7 + 72167 = 72174
13 + 72161 = 72174
71 + 72103 = 72174
73 + 72101 = 72174
83 + 72091 = 72174
97 + 72077 = 72174
101 + 72073 = 72174

Showing the first eight; more decompositions exist.
