Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452982, here are decompositions:

5 + 31452977 = 31452982
131 + 31452851 = 31452982
179 + 31452803 = 31452982
233 + 31452749 = 31452982
251 + 31452731 = 31452982
263 + 31452719 = 31452982
359 + 31452623 = 31452982
383 + 31452599 = 31452982

Showing the first eight; more decompositions exist.
