Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542070, here are decompositions:

3 + 31542067 = 31542070
47 + 31542023 = 31542070
59 + 31542011 = 31542070
89 + 31541981 = 31542070
137 + 31541933 = 31542070
167 + 31541903 = 31542070
179 + 31541891 = 31542070
419 + 31541651 = 31542070

Showing the first eight; more decompositions exist.
