Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149672, here are decompositions:
- 43 + 149629 = 149672
- 109 + 149563 = 149672
- 139 + 149533 = 149672
- 151 + 149521 = 149672
- 181 + 149491 = 149672
- 331 + 149341 = 149672
- 349 + 149323 = 149672
- 421 + 149251 = 149672
Showing the first eight; more decompositions exist.
