Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592900, here are decompositions:

67 + 31592833 = 31592900
103 + 31592797 = 31592900
127 + 31592773 = 31592900
139 + 31592761 = 31592900
223 + 31592677 = 31592900
349 + 31592551 = 31592900
433 + 31592467 = 31592900
463 + 31592437 = 31592900

Showing the first eight; more decompositions exist.
