Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743128, here are decompositions:
- 7 + 8743121 = 8743128
- 29 + 8743099 = 8743128
- 41 + 8743087 = 8743128
- 61 + 8743067 = 8743128
- 101 + 8743027 = 8743128
- 109 + 8743019 = 8743128
- 127 + 8743001 = 8743128
- 131 + 8742997 = 8743128
Showing the first eight; more decompositions exist.
