Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483530, here are decompositions:

37 + 31483493 = 31483530
59 + 31483471 = 31483530
61 + 31483469 = 31483530
73 + 31483457 = 31483530
83 + 31483447 = 31483530
97 + 31483433 = 31483530
101 + 31483429 = 31483530
139 + 31483391 = 31483530

Showing the first eight; more decompositions exist.
