Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502698, here are decompositions:

11 + 31502687 = 31502698
137 + 31502561 = 31502698
239 + 31502459 = 31502698
257 + 31502441 = 31502698
419 + 31502279 = 31502698
509 + 31502189 = 31502698
569 + 31502129 = 31502698
599 + 31502099 = 31502698

Showing the first eight; more decompositions exist.
