Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031730, here are decompositions:
- 13 + 1031717 = 1031730
- 23 + 1031707 = 1031730
- 53 + 1031677 = 1031730
- 61 + 1031669 = 1031730
- 97 + 1031633 = 1031730
- 101 + 1031629 = 1031730
- 107 + 1031623 = 1031730
- 137 + 1031593 = 1031730
Showing the first eight; more decompositions exist.
