Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539044, here are decompositions:
- 37 + 31539007 = 31539044
- 157 + 31538887 = 31539044
- 331 + 31538713 = 31539044
- 373 + 31538671 = 31539044
- 421 + 31538623 = 31539044
- 463 + 31538581 = 31539044
- 487 + 31538557 = 31539044
- 541 + 31538503 = 31539044
Showing the first eight; more decompositions exist.
