Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560754, here are decompositions:

3 + 31560751 = 31560754
23 + 31560731 = 31560754
41 + 31560713 = 31560754
107 + 31560647 = 31560754
167 + 31560587 = 31560754
317 + 31560437 = 31560754
347 + 31560407 = 31560754
353 + 31560401 = 31560754

Showing the first eight; more decompositions exist.
