Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172976, here are decompositions:

3 + 172973 = 172976
7 + 172969 = 172976
43 + 172933 = 172976
109 + 172867 = 172976
127 + 172849 = 172976
313 + 172663 = 172976
373 + 172603 = 172976
379 + 172597 = 172976

Showing the first eight; more decompositions exist.
