Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574098, here are decompositions:

5 + 31574093 = 31574098
131 + 31573967 = 31574098
137 + 31573961 = 31574098
167 + 31573931 = 31574098
239 + 31573859 = 31574098
251 + 31573847 = 31574098
401 + 31573697 = 31574098
419 + 31573679 = 31574098

Showing the first eight; more decompositions exist.
