Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465098, here are decompositions:

29 + 31465069 = 31465098
37 + 31465061 = 31465098
59 + 31465039 = 31465098
107 + 31464991 = 31465098
131 + 31464967 = 31465098
151 + 31464947 = 31465098
157 + 31464941 = 31465098
271 + 31464827 = 31465098

Showing the first eight; more decompositions exist.
