Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501626, here are decompositions:

5 + 31501621 = 31501626
7 + 31501619 = 31501626
43 + 31501583 = 31501626
59 + 31501567 = 31501626
89 + 31501537 = 31501626
103 + 31501523 = 31501626
179 + 31501447 = 31501626
193 + 31501433 = 31501626

Showing the first eight; more decompositions exist.
