Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500344, here are decompositions:

151 + 31500193 = 31500344
157 + 31500187 = 31500344
541 + 31499803 = 31500344
613 + 31499731 = 31500344
751 + 31499593 = 31500344
853 + 31499491 = 31500344
877 + 31499467 = 31500344
937 + 31499407 = 31500344

Showing the first eight; more decompositions exist.
