Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707320, here are decompositions:
- 31 + 8707289 = 8707320
- 43 + 8707277 = 8707320
- 47 + 8707273 = 8707320
- 79 + 8707241 = 8707320
- 101 + 8707219 = 8707320
- 113 + 8707207 = 8707320
- 131 + 8707189 = 8707320
- 137 + 8707183 = 8707320
Showing the first eight; more decompositions exist.
