Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738042, here are decompositions:

31 + 8738011 = 8738042
109 + 8737933 = 8738042
193 + 8737849 = 8738042
199 + 8737843 = 8738042
241 + 8737801 = 8738042
349 + 8737693 = 8738042
373 + 8737669 = 8738042
499 + 8737543 = 8738042

Showing the first eight; more decompositions exist.
