Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147740, here are decompositions:
- 13 + 147727 = 147740
- 31 + 147709 = 147740
- 37 + 147703 = 147740
- 67 + 147673 = 147740
- 79 + 147661 = 147740
- 127 + 147613 = 147740
- 157 + 147583 = 147740
- 193 + 147547 = 147740
Showing the first eight; more decompositions exist.
