Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40152, here are decompositions:
- 23 + 40129 = 40152
- 29 + 40123 = 40152
- 41 + 40111 = 40152
- 53 + 40099 = 40152
- 59 + 40093 = 40152
- 89 + 40063 = 40152
- 113 + 40039 = 40152
- 139 + 40013 = 40152
Showing the first eight; more decompositions exist.
