Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031472, here are decompositions:
- 11 + 1031461 = 1031472
- 41 + 1031431 = 1031472
- 59 + 1031413 = 1031472
- 61 + 1031411 = 1031472
- 73 + 1031399 = 1031472
- 149 + 1031323 = 1031472
- 163 + 1031309 = 1031472
- 173 + 1031299 = 1031472
Showing the first eight; more decompositions exist.
