Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72278, here are decompositions:

7 + 72271 = 72278
67 + 72211 = 72278
109 + 72169 = 72278
139 + 72139 = 72278
307 + 71971 = 72278
331 + 71947 = 72278
337 + 71941 = 72278
379 + 71899 = 72278

Showing the first eight; more decompositions exist.
