Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559044, here are decompositions:
- 17 + 31559027 = 31559044
- 47 + 31558997 = 31559044
- 71 + 31558973 = 31559044
- 197 + 31558847 = 31559044
- 311 + 31558733 = 31559044
- 653 + 31558391 = 31559044
- 761 + 31558283 = 31559044
- 821 + 31558223 = 31559044
Showing the first eight; more decompositions exist.
