Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541504, here are decompositions:

37 + 31541467 = 31541504
67 + 31541437 = 31541504
103 + 31541401 = 31541504
157 + 31541347 = 31541504
223 + 31541281 = 31541504
271 + 31541233 = 31541504
331 + 31541173 = 31541504
433 + 31541071 = 31541504

Showing the first eight; more decompositions exist.
