Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731012, here are decompositions:

29 + 8730983 = 8731012
83 + 8730929 = 8731012
131 + 8730881 = 8731012
149 + 8730863 = 8731012
383 + 8730629 = 8731012
401 + 8730611 = 8731012
659 + 8730353 = 8731012
701 + 8730311 = 8731012

Showing the first eight; more decompositions exist.
