Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579058, here are decompositions:
- 19 + 31579039 = 31579058
- 109 + 31578949 = 31579058
- 139 + 31578919 = 31579058
- 271 + 31578787 = 31579058
- 337 + 31578721 = 31579058
- 367 + 31578691 = 31579058
- 457 + 31578601 = 31579058
- 607 + 31578451 = 31579058
Showing the first eight; more decompositions exist.
