Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488488, here are decompositions:

7 + 31488481 = 31488488
19 + 31488469 = 31488488
277 + 31488211 = 31488488
379 + 31488109 = 31488488
397 + 31488091 = 31488488
457 + 31488031 = 31488488
547 + 31487941 = 31488488
571 + 31487917 = 31488488

Showing the first eight; more decompositions exist.
