Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462608, here are decompositions:

5 + 31462603 = 31462608
17 + 31462591 = 31462608
19 + 31462589 = 31462608
29 + 31462579 = 31462608
31 + 31462577 = 31462608
61 + 31462547 = 31462608
101 + 31462507 = 31462608
127 + 31462481 = 31462608

Showing the first eight; more decompositions exist.
