Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460390, here are decompositions:
- 43 + 31460347 = 31460390
- 61 + 31460329 = 31460390
- 97 + 31460293 = 31460390
- 109 + 31460281 = 31460390
- 127 + 31460263 = 31460390
- 193 + 31460197 = 31460390
- 223 + 31460167 = 31460390
- 337 + 31460053 = 31460390
Showing the first eight; more decompositions exist.
