Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731192, here are decompositions:

5 + 8731187 = 8731192
53 + 8731139 = 8731192
83 + 8731109 = 8731192
89 + 8731103 = 8731192
263 + 8730929 = 8731192
311 + 8730881 = 8731192
389 + 8730803 = 8731192
563 + 8730629 = 8731192

Showing the first eight; more decompositions exist.
