Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551076, here are decompositions:

5 + 31551071 = 31551076
83 + 31550993 = 31551076
197 + 31550879 = 31551076
239 + 31550837 = 31551076
269 + 31550807 = 31551076
353 + 31550723 = 31551076
449 + 31550627 = 31551076
503 + 31550573 = 31551076

Showing the first eight; more decompositions exist.
