Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163740, here are decompositions:
- 7 + 163733 = 163740
- 11 + 163729 = 163740
- 43 + 163697 = 163740
- 61 + 163679 = 163740
- 67 + 163673 = 163740
- 79 + 163661 = 163740
- 97 + 163643 = 163740
- 103 + 163637 = 163740
Showing the first eight; more decompositions exist.
