Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719190, here are decompositions:

3 + 8719187 = 8719190
13 + 8719177 = 8719190
31 + 8719159 = 8719190
241 + 8718949 = 8719190
283 + 8718907 = 8719190
313 + 8718877 = 8719190
331 + 8718859 = 8719190
367 + 8718823 = 8719190

Showing the first eight; more decompositions exist.
