Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71836, here are decompositions:

29 + 71807 = 71836
47 + 71789 = 71836
59 + 71777 = 71836
137 + 71699 = 71836
173 + 71663 = 71836
239 + 71597 = 71836
353 + 71483 = 71836
383 + 71453 = 71836

Showing the first eight; more decompositions exist.
