Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526220, here are decompositions:
- 7 + 31526213 = 31526220
- 13 + 31526207 = 31526220
- 23 + 31526197 = 31526220
- 29 + 31526191 = 31526220
- 31 + 31526189 = 31526220
- 79 + 31526141 = 31526220
- 137 + 31526083 = 31526220
- 151 + 31526069 = 31526220
Showing the first eight; more decompositions exist.
