Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468542, here are decompositions:

13 + 31468529 = 31468542
19 + 31468523 = 31468542
31 + 31468511 = 31468542
43 + 31468499 = 31468542
71 + 31468471 = 31468542
89 + 31468453 = 31468542
139 + 31468403 = 31468542
151 + 31468391 = 31468542

Showing the first eight; more decompositions exist.
