Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607142, here are decompositions:
- 3 + 8607139 = 8607142
- 83 + 8607059 = 8607142
- 113 + 8607029 = 8607142
- 179 + 8606963 = 8607142
- 233 + 8606909 = 8607142
- 353 + 8606789 = 8607142
- 449 + 8606693 = 8607142
- 521 + 8606621 = 8607142
Showing the first eight; more decompositions exist.
