Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145092, here are decompositions:
- 23 + 145069 = 145092
- 29 + 145063 = 145092
- 61 + 145031 = 145092
- 71 + 145021 = 145092
- 83 + 145009 = 145092
- 109 + 144983 = 145092
- 131 + 144961 = 145092
- 151 + 144941 = 145092
Showing the first eight; more decompositions exist.
