Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731088, here are decompositions:

19 + 8731069 = 8731088
61 + 8731027 = 8731088
139 + 8730949 = 8731088
199 + 8730889 = 8731088
229 + 8730859 = 8731088
241 + 8730847 = 8731088
307 + 8730781 = 8731088
397 + 8730691 = 8731088

Showing the first eight; more decompositions exist.
