Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761438, here are decompositions:

5 + 8761433 = 8761438
149 + 8761289 = 8761438
269 + 8761169 = 8761438
281 + 8761157 = 8761438
359 + 8761079 = 8761438
401 + 8761037 = 8761438
419 + 8761019 = 8761438
431 + 8761007 = 8761438

Showing the first eight; more decompositions exist.
