Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612380, here are decompositions:

137 + 8612243 = 8612380
281 + 8612099 = 8612380
347 + 8612033 = 8612380
389 + 8611991 = 8612380
419 + 8611961 = 8612380
521 + 8611859 = 8612380
587 + 8611793 = 8612380
659 + 8611721 = 8612380

Showing the first eight; more decompositions exist.
