Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502694, here are decompositions:

5 + 31502689 = 31502694
7 + 31502687 = 31502694
107 + 31502587 = 31502694
131 + 31502563 = 31502694
137 + 31502557 = 31502694
211 + 31502483 = 31502694
263 + 31502431 = 31502694
331 + 31502363 = 31502694

Showing the first eight; more decompositions exist.
