Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604542, here are decompositions:

41 + 31604501 = 31604542
89 + 31604453 = 31604542
239 + 31604303 = 31604542
353 + 31604189 = 31604542
443 + 31604099 = 31604542
491 + 31604051 = 31604542
509 + 31604033 = 31604542
653 + 31603889 = 31604542

Showing the first eight; more decompositions exist.
