Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678442, here are decompositions:
- 43 + 8678399 = 8678442
- 79 + 8678363 = 8678442
- 83 + 8678359 = 8678442
- 89 + 8678353 = 8678442
- 103 + 8678339 = 8678442
- 109 + 8678333 = 8678442
- 131 + 8678311 = 8678442
- 229 + 8678213 = 8678442
Showing the first eight; more decompositions exist.
