Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72604, here are decompositions:

53 + 72551 = 72604
71 + 72533 = 72604
101 + 72503 = 72604
107 + 72497 = 72604
137 + 72467 = 72604
173 + 72431 = 72604
251 + 72353 = 72604
263 + 72341 = 72604

Showing the first eight; more decompositions exist.
