Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541144, here are decompositions:

3 + 31541141 = 31541144
31 + 31541113 = 31541144
43 + 31541101 = 31541144
73 + 31541071 = 31541144
97 + 31541047 = 31541144
127 + 31541017 = 31541144
223 + 31540921 = 31541144
277 + 31540867 = 31541144

Showing the first eight; more decompositions exist.
