Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29786, here are decompositions:

103 + 29683 = 29786
157 + 29629 = 29786
199 + 29587 = 29786
313 + 29473 = 29786
349 + 29437 = 29786
397 + 29389 = 29786
439 + 29347 = 29786
499 + 29287 = 29786

Showing the first eight; more decompositions exist.
