Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450662, here are decompositions:

41 + 31450621 = 31450662
43 + 31450619 = 31450662
59 + 31450603 = 31450662
73 + 31450589 = 31450662
79 + 31450583 = 31450662
83 + 31450579 = 31450662
179 + 31450483 = 31450662
211 + 31450451 = 31450662

Showing the first eight; more decompositions exist.
