Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502000, here are decompositions:

43 + 31501957 = 31502000
139 + 31501861 = 31502000
151 + 31501849 = 31502000
181 + 31501819 = 31502000
193 + 31501807 = 31502000
241 + 31501759 = 31502000
331 + 31501669 = 31502000
367 + 31501633 = 31502000

Showing the first eight; more decompositions exist.
