Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481094, here are decompositions:

17 + 31481077 = 31481094
37 + 31481057 = 31481094
83 + 31481011 = 31481094
131 + 31480963 = 31481094
181 + 31480913 = 31481094
193 + 31480901 = 31481094
233 + 31480861 = 31481094
331 + 31480763 = 31481094

Showing the first eight; more decompositions exist.
