Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541222, here are decompositions:

43 + 31541179 = 31541222
61 + 31541161 = 31541222
109 + 31541113 = 31541222
151 + 31541071 = 31541222
283 + 31540939 = 31541222
409 + 31540813 = 31541222
439 + 31540783 = 31541222
499 + 31540723 = 31541222

Showing the first eight; more decompositions exist.
