Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731162, here are decompositions:

23 + 8731139 = 8731162
53 + 8731109 = 8731162
59 + 8731103 = 8731162
131 + 8731031 = 8731162
179 + 8730983 = 8731162
233 + 8730929 = 8731162
269 + 8730893 = 8731162
281 + 8730881 = 8731162

Showing the first eight; more decompositions exist.
