Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540132, here are decompositions:
- 23 + 31540109 = 31540132
- 101 + 31540031 = 31540132
- 269 + 31539863 = 31540132
- 293 + 31539839 = 31540132
- 311 + 31539821 = 31540132
- 419 + 31539713 = 31540132
- 461 + 31539671 = 31540132
- 563 + 31539569 = 31540132
Showing the first eight; more decompositions exist.
