Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489244, here are decompositions:

67 + 31489177 = 31489244
97 + 31489147 = 31489244
181 + 31489063 = 31489244
313 + 31488931 = 31489244
337 + 31488907 = 31489244
613 + 31488631 = 31489244
751 + 31488493 = 31489244
811 + 31488433 = 31489244

Showing the first eight; more decompositions exist.
