Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501634, here are decompositions:

13 + 31501621 = 31501634
67 + 31501567 = 31501634
97 + 31501537 = 31501634
103 + 31501531 = 31501634
313 + 31501321 = 31501634
331 + 31501303 = 31501634
433 + 31501201 = 31501634
1171 + 31500463 = 31501634

Showing the first eight; more decompositions exist.
