Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139054, here are decompositions:
- 131 + 138923 = 139054
- 137 + 138917 = 139054
- 191 + 138863 = 139054
- 233 + 138821 = 139054
- 257 + 138797 = 139054
- 467 + 138587 = 139054
- 491 + 138563 = 139054
- 557 + 138497 = 139054
Showing the first eight; more decompositions exist.
