Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40158, here are decompositions:
- 5 + 40153 = 40158
- 7 + 40151 = 40158
- 29 + 40129 = 40158
- 31 + 40127 = 40158
- 47 + 40111 = 40158
- 59 + 40099 = 40158
- 71 + 40087 = 40158
- 127 + 40031 = 40158
Showing the first eight; more decompositions exist.
