Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534964, here are decompositions:

3 + 31534961 = 31534964
163 + 31534801 = 31534964
211 + 31534753 = 31534964
313 + 31534651 = 31534964
367 + 31534597 = 31534964
421 + 31534543 = 31534964
463 + 31534501 = 31534964
523 + 31534441 = 31534964

Showing the first eight; more decompositions exist.
