Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672378, here are decompositions:

31 + 8672347 = 8672378
139 + 8672239 = 8672378
277 + 8672101 = 8672378
331 + 8672047 = 8672378
397 + 8671981 = 8672378
541 + 8671837 = 8672378
709 + 8671669 = 8672378
739 + 8671639 = 8672378

Showing the first eight; more decompositions exist.
