Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149862, here are decompositions:
- 23 + 149839 = 149862
- 59 + 149803 = 149862
- 71 + 149791 = 149862
- 103 + 149759 = 149862
- 113 + 149749 = 149862
- 131 + 149731 = 149862
- 149 + 149713 = 149862
- 151 + 149711 = 149862
Showing the first eight; more decompositions exist.
