Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731298, here are decompositions:

67 + 8731231 = 8731298
97 + 8731201 = 8731298
157 + 8731141 = 8731298
229 + 8731069 = 8731298
271 + 8731027 = 8731298
349 + 8730949 = 8731298
379 + 8730919 = 8731298
397 + 8730901 = 8731298

Showing the first eight; more decompositions exist.
