Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448002, here are decompositions:

41 + 31447961 = 31448002
71 + 31447931 = 31448002
101 + 31447901 = 31448002
149 + 31447853 = 31448002
191 + 31447811 = 31448002
233 + 31447769 = 31448002
251 + 31447751 = 31448002
359 + 31447643 = 31448002

Showing the first eight; more decompositions exist.
