Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450692, here are decompositions:

71 + 31450621 = 31450692
73 + 31450619 = 31450692
79 + 31450613 = 31450692
89 + 31450603 = 31450692
103 + 31450589 = 31450692
109 + 31450583 = 31450692
113 + 31450579 = 31450692
149 + 31450543 = 31450692

Showing the first eight; more decompositions exist.
