Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72670, here are decompositions:

23 + 72647 = 72670
47 + 72623 = 72670
53 + 72617 = 72670
137 + 72533 = 72670
167 + 72503 = 72670
173 + 72497 = 72670
239 + 72431 = 72670
317 + 72353 = 72670

Showing the first eight; more decompositions exist.
