Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 181174, here are decompositions:

17 + 181157 = 181174
113 + 181061 = 181174
173 + 181001 = 181174
401 + 180773 = 181174
443 + 180731 = 181174
557 + 180617 = 181174
641 + 180533 = 181174
677 + 180497 = 181174

Showing the first eight; more decompositions exist.
