Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541136, here are decompositions:
- 7 + 31541129 = 31541136
- 19 + 31541117 = 31541136
- 23 + 31541113 = 31541136
- 89 + 31541047 = 31541136
- 97 + 31541039 = 31541136
- 157 + 31540979 = 31541136
- 197 + 31540939 = 31541136
- 269 + 31540867 = 31541136
Showing the first eight; more decompositions exist.
