Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 53742, here are decompositions:
- 11 + 53731 = 53742
- 23 + 53719 = 53742
- 43 + 53699 = 53742
- 61 + 53681 = 53742
- 89 + 53653 = 53742
- 103 + 53639 = 53742
- 109 + 53633 = 53742
- 113 + 53629 = 53742
Showing the first eight; more decompositions exist.
