Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40172, here are decompositions:
- 3 + 40169 = 40172
- 19 + 40153 = 40172
- 43 + 40129 = 40172
- 61 + 40111 = 40172
- 73 + 40099 = 40172
- 79 + 40093 = 40172
- 109 + 40063 = 40172
- 163 + 40009 = 40172
Showing the first eight; more decompositions exist.
