Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499132, here are decompositions:

109 + 31499023 = 31499132
139 + 31498993 = 31499132
283 + 31498849 = 31499132
541 + 31498591 = 31499132
619 + 31498513 = 31499132
661 + 31498471 = 31499132
853 + 31498279 = 31499132
859 + 31498273 = 31499132

Showing the first eight; more decompositions exist.
