Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731004, here are decompositions:

103 + 8730901 = 8731004
157 + 8730847 = 8731004
211 + 8730793 = 8731004
223 + 8730781 = 8731004
307 + 8730697 = 8731004
313 + 8730691 = 8731004
397 + 8730607 = 8731004
421 + 8730583 = 8731004

Showing the first eight; more decompositions exist.
