Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453030, here are decompositions:

53 + 31452977 = 31453030
179 + 31452851 = 31453030
227 + 31452803 = 31453030
281 + 31452749 = 31453030
311 + 31452719 = 31453030
347 + 31452683 = 31453030
353 + 31452677 = 31453030
431 + 31452599 = 31453030

Showing the first eight; more decompositions exist.
