Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148772, here are decompositions:
- 61 + 148711 = 148772
- 79 + 148693 = 148772
- 103 + 148669 = 148772
- 109 + 148663 = 148772
- 139 + 148633 = 148772
- 163 + 148609 = 148772
- 193 + 148579 = 148772
- 199 + 148573 = 148772
Showing the first eight; more decompositions exist.
