Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701538, here are decompositions:

7 + 8701531 = 8701538
19 + 8701519 = 8701538
31 + 8701507 = 8701538
61 + 8701477 = 8701538
229 + 8701309 = 8701538
271 + 8701267 = 8701538
331 + 8701207 = 8701538
397 + 8701141 = 8701538

Showing the first eight; more decompositions exist.
