Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534376, here are decompositions:

7 + 31534369 = 31534376
43 + 31534333 = 31534376
79 + 31534297 = 31534376
193 + 31534183 = 31534376
397 + 31533979 = 31534376
409 + 31533967 = 31534376
457 + 31533919 = 31534376
547 + 31533829 = 31534376

Showing the first eight; more decompositions exist.
