Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540446, here are decompositions:
- 5 + 31540441 = 31540446
- 29 + 31540417 = 31540446
- 83 + 31540363 = 31540446
- 103 + 31540343 = 31540446
- 107 + 31540339 = 31540446
- 137 + 31540309 = 31540446
- 149 + 31540297 = 31540446
- 229 + 31540217 = 31540446
Showing the first eight; more decompositions exist.
