Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670978, here are decompositions:
- 31 + 8670947 = 8670978
- 37 + 8670941 = 8670978
- 59 + 8670919 = 8670978
- 109 + 8670869 = 8670978
- 167 + 8670811 = 8670978
- 227 + 8670751 = 8670978
- 269 + 8670709 = 8670978
- 311 + 8670667 = 8670978
Showing the first eight; more decompositions exist.
