Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448104, here are decompositions:

47 + 31448057 = 31448104
71 + 31448033 = 31448104
137 + 31447967 = 31448104
173 + 31447931 = 31448104
251 + 31447853 = 31448104
293 + 31447811 = 31448104
353 + 31447751 = 31448104
431 + 31447673 = 31448104

Showing the first eight; more decompositions exist.
