Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517144, here are decompositions:

151 + 31516993 = 31517144
163 + 31516981 = 31517144
193 + 31516951 = 31517144
367 + 31516777 = 31517144
541 + 31516603 = 31517144
577 + 31516567 = 31517144
601 + 31516543 = 31517144
643 + 31516501 = 31517144

Showing the first eight; more decompositions exist.
