Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502300, here are decompositions:

13 + 31502287 = 31502300
31 + 31502269 = 31502300
139 + 31502161 = 31502300
421 + 31501879 = 31502300
439 + 31501861 = 31502300
541 + 31501759 = 31502300
601 + 31501699 = 31502300
631 + 31501669 = 31502300

Showing the first eight; more decompositions exist.
