Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137912, here are decompositions:
- 3 + 137909 = 137912
- 43 + 137869 = 137912
- 109 + 137803 = 137912
- 199 + 137713 = 137912
- 421 + 137491 = 137912
- 499 + 137413 = 137912
- 571 + 137341 = 137912
- 661 + 137251 = 137912
Showing the first eight; more decompositions exist.
