Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502562, here are decompositions:

5 + 31502557 = 31502562
23 + 31502539 = 31502562
29 + 31502533 = 31502562
73 + 31502489 = 31502562
79 + 31502483 = 31502562
103 + 31502459 = 31502562
131 + 31502431 = 31502562
191 + 31502371 = 31502562

Showing the first eight; more decompositions exist.
