Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502062, here are decompositions:

83 + 31501979 = 31502062
149 + 31501913 = 31502062
239 + 31501823 = 31502062
281 + 31501781 = 31502062
311 + 31501751 = 31502062
401 + 31501661 = 31502062
443 + 31501619 = 31502062
479 + 31501583 = 31502062

Showing the first eight; more decompositions exist.
