Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592200, here are decompositions:

41 + 31592159 = 31592200
71 + 31592129 = 31592200
149 + 31592051 = 31592200
449 + 31591751 = 31592200
461 + 31591739 = 31592200
467 + 31591733 = 31592200
599 + 31591601 = 31592200
683 + 31591517 = 31592200

Showing the first eight; more decompositions exist.
