Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462582, here are decompositions:

3 + 31462579 = 31462582
5 + 31462577 = 31462582
29 + 31462553 = 31462582
101 + 31462481 = 31462582
131 + 31462451 = 31462582
149 + 31462433 = 31462582
233 + 31462349 = 31462582
269 + 31462313 = 31462582

Showing the first eight; more decompositions exist.
