Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534814, here are decompositions:

13 + 31534801 = 31534814
61 + 31534753 = 31534814
163 + 31534651 = 31534814
271 + 31534543 = 31534814
313 + 31534501 = 31534814
331 + 31534483 = 31534814
373 + 31534441 = 31534814
631 + 31534183 = 31534814

Showing the first eight; more decompositions exist.
