Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145862, here are decompositions:
- 43 + 145819 = 145862
- 103 + 145759 = 145862
- 109 + 145753 = 145862
- 139 + 145723 = 145862
- 181 + 145681 = 145862
- 229 + 145633 = 145862
- 313 + 145549 = 145862
- 331 + 145531 = 145862
Showing the first eight; more decompositions exist.
