Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486176, here are decompositions:
- 13 + 31486163 = 31486176
- 47 + 31486129 = 31486176
- 53 + 31486123 = 31486176
- 67 + 31486109 = 31486176
- 89 + 31486087 = 31486176
- 167 + 31486009 = 31486176
- 223 + 31485953 = 31486176
- 283 + 31485893 = 31486176
Showing the first eight; more decompositions exist.
