Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448254, here are decompositions:

53 + 31448201 = 31448254
83 + 31448171 = 31448254
113 + 31448141 = 31448254
197 + 31448057 = 31448254
293 + 31447961 = 31448254
353 + 31447901 = 31448254
401 + 31447853 = 31448254
443 + 31447811 = 31448254

Showing the first eight; more decompositions exist.
