Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541150, here are decompositions:

37 + 31541113 = 31541150
79 + 31541071 = 31541150
103 + 31541047 = 31541150
211 + 31540939 = 31541150
229 + 31540921 = 31541150
283 + 31540867 = 31541150
313 + 31540837 = 31541150
337 + 31540813 = 31541150

Showing the first eight; more decompositions exist.
