Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540248, here are decompositions:
- 7 + 31540241 = 31540248
- 31 + 31540217 = 31540248
- 37 + 31540211 = 31540248
- 41 + 31540207 = 31540248
- 59 + 31540189 = 31540248
- 67 + 31540181 = 31540248
- 101 + 31540147 = 31540248
- 139 + 31540109 = 31540248
Showing the first eight; more decompositions exist.
