Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452802, here are decompositions:

53 + 31452749 = 31452802
71 + 31452731 = 31452802
83 + 31452719 = 31452802
179 + 31452623 = 31452802
263 + 31452539 = 31452802
281 + 31452521 = 31452802
383 + 31452419 = 31452802
401 + 31452401 = 31452802

Showing the first eight; more decompositions exist.
