Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502498, here are decompositions:

67 + 31502431 = 31502498
127 + 31502371 = 31502498
211 + 31502287 = 31502498
229 + 31502269 = 31502498
337 + 31502161 = 31502498
367 + 31502131 = 31502498
541 + 31501957 = 31502498
619 + 31501879 = 31502498

Showing the first eight; more decompositions exist.
