Goldbach decomposition

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.
