Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40472, here are decompositions:
- 13 + 40459 = 40472
- 43 + 40429 = 40472
- 241 + 40231 = 40472
- 283 + 40189 = 40472
- 349 + 40123 = 40472
- 373 + 40099 = 40472
- 379 + 40093 = 40472
- 409 + 40063 = 40472
Showing the first eight; more decompositions exist.
