Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707688, here are decompositions:
- 19 + 8707669 = 8707688
- 37 + 8707651 = 8707688
- 97 + 8707591 = 8707688
- 109 + 8707579 = 8707688
- 151 + 8707537 = 8707688
- 211 + 8707477 = 8707688
- 331 + 8707357 = 8707688
- 337 + 8707351 = 8707688
Showing the first eight; more decompositions exist.
