Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155792, here are decompositions:
- 19 + 155773 = 155792
- 61 + 155731 = 155792
- 73 + 155719 = 155792
- 103 + 155689 = 155792
- 139 + 155653 = 155792
- 193 + 155599 = 155792
- 199 + 155593 = 155792
- 211 + 155581 = 155792
Showing the first eight; more decompositions exist.
