Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31587902, here are decompositions:
- 43 + 31587859 = 31587902
- 103 + 31587799 = 31587902
- 109 + 31587793 = 31587902
- 613 + 31587289 = 31587902
- 631 + 31587271 = 31587902
- 751 + 31587151 = 31587902
- 811 + 31587091 = 31587902
- 883 + 31587019 = 31587902
Showing the first eight; more decompositions exist.
