Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452898, here are decompositions:

47 + 31452851 = 31452898
149 + 31452749 = 31452898
167 + 31452731 = 31452898
179 + 31452719 = 31452898
311 + 31452587 = 31452898
359 + 31452539 = 31452898
401 + 31452497 = 31452898
479 + 31452419 = 31452898

Showing the first eight; more decompositions exist.
