Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531604, here are decompositions:

151 + 31531453 = 31531604
331 + 31531273 = 31531604
337 + 31531267 = 31531604
487 + 31531117 = 31531604
541 + 31531063 = 31531604
547 + 31531057 = 31531604
631 + 31530973 = 31531604
661 + 31530943 = 31531604

Showing the first eight; more decompositions exist.
