Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538504, here are decompositions:

13 + 31538491 = 31538504
31 + 31538473 = 31538504
61 + 31538443 = 31538504
97 + 31538407 = 31538504
367 + 31538137 = 31538504
373 + 31538131 = 31538504
397 + 31538107 = 31538504
433 + 31538071 = 31538504

Showing the first eight; more decompositions exist.
