Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502434, here are decompositions:

3 + 31502431 = 31502434
71 + 31502363 = 31502434
101 + 31502333 = 31502434
191 + 31502243 = 31502434
251 + 31502183 = 31502434
521 + 31501913 = 31502434
653 + 31501781 = 31502434
683 + 31501751 = 31502434

Showing the first eight; more decompositions exist.
