Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149072, here are decompositions:
- 3 + 149069 = 149072
- 13 + 149059 = 149072
- 19 + 149053 = 149072
- 61 + 149011 = 149072
- 139 + 148933 = 149072
- 151 + 148921 = 149072
- 181 + 148891 = 149072
- 199 + 148873 = 149072
Showing the first eight; more decompositions exist.
