Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558504, here are decompositions:

41 + 31558463 = 31558504
71 + 31558433 = 31558504
113 + 31558391 = 31558504
167 + 31558337 = 31558504
251 + 31558253 = 31558504
281 + 31558223 = 31558504
293 + 31558211 = 31558504
317 + 31558187 = 31558504

Showing the first eight; more decompositions exist.
