Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540344, here are decompositions:
- 5 + 31540339 = 31540344
- 47 + 31540297 = 31540344
- 83 + 31540261 = 31540344
- 103 + 31540241 = 31540344
- 127 + 31540217 = 31540344
- 131 + 31540213 = 31540344
- 137 + 31540207 = 31540344
- 163 + 31540181 = 31540344
Showing the first eight; more decompositions exist.
