Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500374, here are decompositions:

7 + 31500367 = 31500374
13 + 31500361 = 31500374
181 + 31500193 = 31500374
541 + 31499833 = 31500374
571 + 31499803 = 31500374
613 + 31499761 = 31500374
643 + 31499731 = 31500374
877 + 31499497 = 31500374

Showing the first eight; more decompositions exist.
