Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61982, here are decompositions:
- 3 + 61979 = 61982
- 73 + 61909 = 61982
- 103 + 61879 = 61982
- 139 + 61843 = 61982
- 163 + 61819 = 61982
- 331 + 61651 = 61982
- 373 + 61609 = 61982
- 379 + 61603 = 61982
Showing the first eight; more decompositions exist.
