Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761312, here are decompositions:

23 + 8761289 = 8761312
59 + 8761253 = 8761312
173 + 8761139 = 8761312
179 + 8761133 = 8761312
233 + 8761079 = 8761312
293 + 8761019 = 8761312
353 + 8760959 = 8761312
389 + 8760923 = 8761312

Showing the first eight; more decompositions exist.
