Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462488, here are decompositions:

7 + 31462481 = 31462488
17 + 31462471 = 31462488
37 + 31462451 = 31462488
47 + 31462441 = 31462488
107 + 31462381 = 31462488
131 + 31462357 = 31462488
137 + 31462351 = 31462488
139 + 31462349 = 31462488

Showing the first eight; more decompositions exist.
