Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582504, here are decompositions:

101 + 31582403 = 31582504
167 + 31582337 = 31582504
263 + 31582241 = 31582504
311 + 31582193 = 31582504
383 + 31582121 = 31582504
461 + 31582043 = 31582504
467 + 31582037 = 31582504
521 + 31581983 = 31582504

Showing the first eight; more decompositions exist.
