Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7156, here are decompositions:
- 5 + 7151 = 7156
- 29 + 7127 = 7156
- 47 + 7109 = 7156
- 53 + 7103 = 7156
- 113 + 7043 = 7156
- 137 + 7019 = 7156
- 173 + 6983 = 7156
- 179 + 6977 = 7156
Showing the first eight; more decompositions exist.
