Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668442, here are decompositions:
- 19 + 8668423 = 8668442
- 61 + 8668381 = 8668442
- 73 + 8668369 = 8668442
- 163 + 8668279 = 8668442
- 241 + 8668201 = 8668442
- 331 + 8668111 = 8668442
- 379 + 8668063 = 8668442
- 463 + 8667979 = 8668442
Showing the first eight; more decompositions exist.
