Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31862, here are decompositions:

3 + 31859 = 31862
13 + 31849 = 31862
139 + 31723 = 31862
163 + 31699 = 31862
199 + 31663 = 31862
331 + 31531 = 31862
349 + 31513 = 31862
373 + 31489 = 31862

Showing the first eight; more decompositions exist.
