Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544190, here are decompositions:
- 11 + 31544179 = 31544190
- 19 + 31544171 = 31544190
- 23 + 31544167 = 31544190
- 37 + 31544153 = 31544190
- 59 + 31544131 = 31544190
- 101 + 31544089 = 31544190
- 113 + 31544077 = 31544190
- 137 + 31544053 = 31544190
Showing the first eight; more decompositions exist.
