Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612392, here are decompositions:

149 + 8612243 = 8612392
293 + 8612099 = 8612392
353 + 8612039 = 8612392
359 + 8612033 = 8612392
401 + 8611991 = 8612392
431 + 8611961 = 8612392
563 + 8611829 = 8612392
599 + 8611793 = 8612392

Showing the first eight; more decompositions exist.
