Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469150, here are decompositions:

7 + 31469143 = 31469150
19 + 31469131 = 31469150
109 + 31469041 = 31469150
157 + 31468993 = 31469150
373 + 31468777 = 31469150
577 + 31468573 = 31469150
607 + 31468543 = 31469150
751 + 31468399 = 31469150

Showing the first eight; more decompositions exist.
