Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001378, here are decompositions:
- 31 + 1001347 = 1001378
- 67 + 1001311 = 1001378
- 181 + 1001197 = 1001378
- 271 + 1001107 = 1001378
- 337 + 1001041 = 1001378
- 379 + 1000999 = 1001378
- 397 + 1000981 = 1001378
- 409 + 1000969 = 1001378
Showing the first eight; more decompositions exist.
