Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543236, here are decompositions:
- 5 + 31543231 = 31543236
- 13 + 31543223 = 31543236
- 17 + 31543219 = 31543236
- 19 + 31543217 = 31543236
- 29 + 31543207 = 31543236
- 73 + 31543163 = 31543236
- 103 + 31543133 = 31543236
- 157 + 31543079 = 31543236
Showing the first eight; more decompositions exist.
