Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527608, here are decompositions:
- 31 + 31527577 = 31527608
- 67 + 31527541 = 31527608
- 109 + 31527499 = 31527608
- 127 + 31527481 = 31527608
- 331 + 31527277 = 31527608
- 397 + 31527211 = 31527608
- 457 + 31527151 = 31527608
- 499 + 31527109 = 31527608
Showing the first eight; more decompositions exist.
