Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637408, here are decompositions:
- 29 + 8637379 = 8637408
- 67 + 8637341 = 8637408
- 71 + 8637337 = 8637408
- 89 + 8637319 = 8637408
- 97 + 8637311 = 8637408
- 107 + 8637301 = 8637408
- 151 + 8637257 = 8637408
- 181 + 8637227 = 8637408
Showing the first eight; more decompositions exist.
