Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83812, here are decompositions:

149 + 83663 = 83812
173 + 83639 = 83812
191 + 83621 = 83812
233 + 83579 = 83812
251 + 83561 = 83812
353 + 83459 = 83812
389 + 83423 = 83812
569 + 83243 = 83812

Showing the first eight; more decompositions exist.
