Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671742, here are decompositions:
- 3 + 8671739 = 8671742
- 31 + 8671711 = 8671742
- 73 + 8671669 = 8671742
- 103 + 8671639 = 8671742
- 109 + 8671633 = 8671742
- 193 + 8671549 = 8671742
- 223 + 8671519 = 8671742
- 241 + 8671501 = 8671742
Showing the first eight; more decompositions exist.
