Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72500, here are decompositions:

3 + 72497 = 72500
7 + 72493 = 72500
19 + 72481 = 72500
31 + 72469 = 72500
79 + 72421 = 72500
163 + 72337 = 72500
193 + 72307 = 72500
223 + 72277 = 72500

Showing the first eight; more decompositions exist.
