Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462494, here are decompositions:

13 + 31462481 = 31462494
23 + 31462471 = 31462494
43 + 31462451 = 31462494
53 + 31462441 = 31462494
61 + 31462433 = 31462494
113 + 31462381 = 31462494
131 + 31462363 = 31462494
137 + 31462357 = 31462494

Showing the first eight; more decompositions exist.
