Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74172, here are decompositions:
- 5 + 74167 = 74172
- 11 + 74161 = 74172
- 13 + 74159 = 74172
- 23 + 74149 = 74172
- 29 + 74143 = 74172
- 41 + 74131 = 74172
- 71 + 74101 = 74172
- 73 + 74099 = 74172
Showing the first eight; more decompositions exist.
