Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761390, here are decompositions:

101 + 8761289 = 8761390
137 + 8761253 = 8761390
233 + 8761157 = 8761390
251 + 8761139 = 8761390
257 + 8761133 = 8761390
311 + 8761079 = 8761390
353 + 8761037 = 8761390
383 + 8761007 = 8761390

Showing the first eight; more decompositions exist.
