Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40478, here are decompositions:
- 7 + 40471 = 40478
- 19 + 40459 = 40478
- 127 + 40351 = 40478
- 241 + 40237 = 40478
- 349 + 40129 = 40478
- 367 + 40111 = 40478
- 379 + 40099 = 40478
- 439 + 40039 = 40478
Showing the first eight; more decompositions exist.
