Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473194, here are decompositions:
- 3 + 31473191 = 31473194
- 7 + 31473187 = 31473194
- 31 + 31473163 = 31473194
- 43 + 31473151 = 31473194
- 127 + 31473067 = 31473194
- 157 + 31473037 = 31473194
- 163 + 31473031 = 31473194
- 211 + 31472983 = 31473194
Showing the first eight; more decompositions exist.
