Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31844, here are decompositions:

73 + 31771 = 31844
103 + 31741 = 31844
157 + 31687 = 31844
181 + 31663 = 31844
271 + 31573 = 31844
277 + 31567 = 31844
313 + 31531 = 31844
331 + 31513 = 31844

Showing the first eight; more decompositions exist.
