Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502734, here are decompositions:

47 + 31502687 = 31502734
173 + 31502561 = 31502734
251 + 31502483 = 31502734
293 + 31502441 = 31502734
401 + 31502333 = 31502734
491 + 31502243 = 31502734
521 + 31502213 = 31502734
587 + 31502147 = 31502734

Showing the first eight; more decompositions exist.
