Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31491176, here are decompositions:

97 + 31491079 = 31491176
193 + 31490983 = 31491176
397 + 31490779 = 31491176
463 + 31490713 = 31491176
499 + 31490677 = 31491176
547 + 31490629 = 31491176
853 + 31490323 = 31491176
877 + 31490299 = 31491176

Showing the first eight; more decompositions exist.
