Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498190, here are decompositions:
- 67 + 31498123 = 31498190
- 79 + 31498111 = 31498190
- 103 + 31498087 = 31498190
- 151 + 31498039 = 31498190
- 181 + 31498009 = 31498190
- 193 + 31497997 = 31498190
- 211 + 31497979 = 31498190
- 307 + 31497883 = 31498190
Showing the first eight; more decompositions exist.
