Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612242, here are decompositions:

251 + 8611991 = 8612242
281 + 8611961 = 8612242
383 + 8611859 = 8612242
449 + 8611793 = 8612242
521 + 8611721 = 8612242
563 + 8611679 = 8612242
599 + 8611643 = 8612242
641 + 8611601 = 8612242

Showing the first eight; more decompositions exist.
