Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544978, here are decompositions:
- 37 + 31544941 = 31544978
- 79 + 31544899 = 31544978
- 151 + 31544827 = 31544978
- 229 + 31544749 = 31544978
- 607 + 31544371 = 31544978
- 631 + 31544347 = 31544978
- 757 + 31544221 = 31544978
- 811 + 31544167 = 31544978
Showing the first eight; more decompositions exist.
