Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452952, here are decompositions:

101 + 31452851 = 31452952
149 + 31452803 = 31452952
233 + 31452719 = 31452952
269 + 31452683 = 31452952
353 + 31452599 = 31452952
431 + 31452521 = 31452952
491 + 31452461 = 31452952
719 + 31452233 = 31452952

Showing the first eight; more decompositions exist.
