Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72550, here are decompositions:

3 + 72547 = 72550
17 + 72533 = 72550
47 + 72503 = 72550
53 + 72497 = 72550
83 + 72467 = 72550
89 + 72461 = 72550
167 + 72383 = 72550
197 + 72353 = 72550

Showing the first eight; more decompositions exist.
