Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708440, here are decompositions:
- 11 + 8708429 = 8708440
- 17 + 8708423 = 8708440
- 29 + 8708411 = 8708440
- 47 + 8708393 = 8708440
- 53 + 8708387 = 8708440
- 101 + 8708339 = 8708440
- 149 + 8708291 = 8708440
- 179 + 8708261 = 8708440
Showing the first eight; more decompositions exist.
