Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502826, here are decompositions:

83 + 31502743 = 31502826
127 + 31502699 = 31502826
137 + 31502689 = 31502826
139 + 31502687 = 31502826
167 + 31502659 = 31502826
239 + 31502587 = 31502826
263 + 31502563 = 31502826
269 + 31502557 = 31502826

Showing the first eight; more decompositions exist.
