Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544128, here are decompositions:
- 29 + 31544099 = 31544128
- 71 + 31544057 = 31544128
- 89 + 31544039 = 31544128
- 107 + 31544021 = 31544128
- 131 + 31543997 = 31544128
- 137 + 31543991 = 31544128
- 149 + 31543979 = 31544128
- 167 + 31543961 = 31544128
Showing the first eight; more decompositions exist.
