Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40194, here are decompositions:
- 5 + 40189 = 40194
- 17 + 40177 = 40194
- 31 + 40163 = 40194
- 41 + 40153 = 40194
- 43 + 40151 = 40194
- 67 + 40127 = 40194
- 71 + 40123 = 40194
- 83 + 40111 = 40194
Showing the first eight; more decompositions exist.
