Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562746, here are decompositions:

179 + 31562567 = 31562746
227 + 31562519 = 31562746
263 + 31562483 = 31562746
317 + 31562429 = 31562746
389 + 31562357 = 31562746
503 + 31562243 = 31562746
647 + 31562099 = 31562746
653 + 31562093 = 31562746

Showing the first eight; more decompositions exist.
