Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40508, here are decompositions:
- 37 + 40471 = 40508
- 79 + 40429 = 40508
- 151 + 40357 = 40508
- 157 + 40351 = 40508
- 271 + 40237 = 40508
- 277 + 40231 = 40508
- 331 + 40177 = 40508
- 379 + 40129 = 40508
Showing the first eight; more decompositions exist.
