Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588040, here are decompositions:
- 37 + 31588003 = 31588040
- 61 + 31587979 = 31588040
- 79 + 31587961 = 31588040
- 97 + 31587943 = 31588040
- 163 + 31587877 = 31588040
- 181 + 31587859 = 31588040
- 223 + 31587817 = 31588040
- 241 + 31587799 = 31588040
Showing the first eight; more decompositions exist.
