Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145662, here are decompositions:
- 19 + 145643 = 145662
- 29 + 145633 = 145662
- 59 + 145603 = 145662
- 61 + 145601 = 145662
- 73 + 145589 = 145662
- 113 + 145549 = 145662
- 131 + 145531 = 145662
- 149 + 145513 = 145662
Showing the first eight; more decompositions exist.
