Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448804, here are decompositions:

97 + 31448707 = 31448804
157 + 31448647 = 31448804
223 + 31448581 = 31448804
271 + 31448533 = 31448804
523 + 31448281 = 31448804
571 + 31448233 = 31448804
613 + 31448191 = 31448804
643 + 31448161 = 31448804

Showing the first eight; more decompositions exist.
