Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156126, here are decompositions:
- 7 + 156119 = 156126
- 17 + 156109 = 156126
- 37 + 156089 = 156126
- 67 + 156059 = 156126
- 107 + 156019 = 156126
- 233 + 155893 = 156126
- 239 + 155887 = 156126
- 263 + 155863 = 156126
Showing the first eight; more decompositions exist.
