Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731264, here are decompositions:

53 + 8731211 = 8731264
167 + 8731097 = 8731264
233 + 8731031 = 8731264
281 + 8730983 = 8731264
317 + 8730947 = 8731264
383 + 8730881 = 8731264
401 + 8730863 = 8731264
461 + 8730803 = 8731264

Showing the first eight; more decompositions exist.
