Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61972, here are decompositions:
- 5 + 61967 = 61972
- 11 + 61961 = 61972
- 23 + 61949 = 61972
- 101 + 61871 = 61972
- 191 + 61781 = 61972
- 269 + 61703 = 61972
- 359 + 61613 = 61972
- 389 + 61583 = 61972
Showing the first eight; more decompositions exist.
