Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678142, here are decompositions:
- 13 + 8678129 = 8678142
- 29 + 8678113 = 8678142
- 59 + 8678083 = 8678142
- 61 + 8678081 = 8678142
- 73 + 8678069 = 8678142
- 79 + 8678063 = 8678142
- 89 + 8678053 = 8678142
- 103 + 8678039 = 8678142
Showing the first eight; more decompositions exist.
