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.
