Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544930, here are decompositions:
- 7 + 31544923 = 31544930
- 31 + 31544899 = 31544930
- 73 + 31544857 = 31544930
- 103 + 31544827 = 31544930
- 181 + 31544749 = 31544930
- 211 + 31544719 = 31544930
- 379 + 31544551 = 31544930
- 397 + 31544533 = 31544930
Showing the first eight; more decompositions exist.
