Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502754, here are decompositions:

11 + 31502743 = 31502754
53 + 31502701 = 31502754
67 + 31502687 = 31502754
167 + 31502587 = 31502754
191 + 31502563 = 31502754
193 + 31502561 = 31502754
197 + 31502557 = 31502754
271 + 31502483 = 31502754

Showing the first eight; more decompositions exist.
