Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542510, here are decompositions:

23 + 31542487 = 31542510
31 + 31542479 = 31542510
53 + 31542457 = 31542510
71 + 31542439 = 31542510
73 + 31542437 = 31542510
113 + 31542397 = 31542510
137 + 31542373 = 31542510
151 + 31542359 = 31542510

Showing the first eight; more decompositions exist.
