Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707378, here are decompositions:

89 + 8707289 = 8707378
101 + 8707277 = 8707378
137 + 8707241 = 8707378
347 + 8707031 = 8707378
431 + 8706947 = 8707378
509 + 8706869 = 8707378
587 + 8706791 = 8707378
809 + 8706569 = 8707378

Showing the first eight; more decompositions exist.
