Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502692, here are decompositions:

3 + 31502689 = 31502692
5 + 31502687 = 31502692
131 + 31502561 = 31502692
233 + 31502459 = 31502692
251 + 31502441 = 31502692
359 + 31502333 = 31502692
449 + 31502243 = 31502692
479 + 31502213 = 31502692

Showing the first eight; more decompositions exist.
