Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448100, here are decompositions:

29 + 31448071 = 31448100
31 + 31448069 = 31448100
43 + 31448057 = 31448100
67 + 31448033 = 31448100
83 + 31448017 = 31448100
113 + 31447987 = 31448100
137 + 31447963 = 31448100
139 + 31447961 = 31448100

Showing the first eight; more decompositions exist.
