Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997154, here are decompositions:

3 + 997151 = 997154
7 + 997147 = 997154
13 + 997141 = 997154
31 + 997123 = 997154
43 + 997111 = 997154
73 + 997081 = 997154
97 + 997057 = 997154
181 + 996973 = 997154

Showing the first eight; more decompositions exist.
