Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540038, here are decompositions:
- 7 + 31540031 = 31540038
- 29 + 31540009 = 31540038
- 31 + 31540007 = 31540038
- 67 + 31539971 = 31540038
- 71 + 31539967 = 31540038
- 107 + 31539931 = 31540038
- 137 + 31539901 = 31540038
- 149 + 31539889 = 31540038
Showing the first eight; more decompositions exist.
