Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72848, here are decompositions:

31 + 72817 = 72848
109 + 72739 = 72848
199 + 72649 = 72848
271 + 72577 = 72848
367 + 72481 = 72848
379 + 72469 = 72848
541 + 72307 = 72848
571 + 72277 = 72848

Showing the first eight; more decompositions exist.
