Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670138, here are decompositions:
- 11 + 8670127 = 8670138
- 31 + 8670107 = 8670138
- 67 + 8670071 = 8670138
- 97 + 8670041 = 8670138
- 101 + 8670037 = 8670138
- 107 + 8670031 = 8670138
- 109 + 8670029 = 8670138
- 131 + 8670007 = 8670138
Showing the first eight; more decompositions exist.
