Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506762, here are decompositions:

13 + 31506749 = 31506762
19 + 31506743 = 31506762
43 + 31506719 = 31506762
73 + 31506689 = 31506762
163 + 31506599 = 31506762
193 + 31506569 = 31506762
233 + 31506529 = 31506762
239 + 31506523 = 31506762

Showing the first eight; more decompositions exist.
