Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478444, here are decompositions:
- 43 + 31478401 = 31478444
- 73 + 31478371 = 31478444
- 103 + 31478341 = 31478444
- 157 + 31478287 = 31478444
- 271 + 31478173 = 31478444
- 367 + 31478077 = 31478444
- 421 + 31478023 = 31478444
- 691 + 31477753 = 31478444
Showing the first eight; more decompositions exist.
