Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554070, here are decompositions:

59 + 31554011 = 31554070
83 + 31553987 = 31554070
167 + 31553903 = 31554070
263 + 31553807 = 31554070
269 + 31553801 = 31554070
293 + 31553777 = 31554070
311 + 31553759 = 31554070
461 + 31553609 = 31554070

Showing the first eight; more decompositions exist.
