Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708390, here are decompositions:

3 + 8708387 = 8708390
193 + 8708197 = 8708390
373 + 8708017 = 8708390
421 + 8707969 = 8708390
487 + 8707903 = 8708390
547 + 8707843 = 8708390
643 + 8707747 = 8708390
739 + 8707651 = 8708390

Showing the first eight; more decompositions exist.
