Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522004, here are decompositions:

13 + 31521991 = 31522004
211 + 31521793 = 31522004
331 + 31521673 = 31522004
337 + 31521667 = 31522004
433 + 31521571 = 31522004
463 + 31521541 = 31522004
523 + 31521481 = 31522004
571 + 31521433 = 31522004

Showing the first eight; more decompositions exist.
