Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544318, here are decompositions:
- 7 + 31544311 = 31544318
- 37 + 31544281 = 31544318
- 97 + 31544221 = 31544318
- 139 + 31544179 = 31544318
- 151 + 31544167 = 31544318
- 229 + 31544089 = 31544318
- 241 + 31544077 = 31544318
- 277 + 31544041 = 31544318
Showing the first eight; more decompositions exist.
