Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465172, here are decompositions:

19 + 31465153 = 31465172
43 + 31465129 = 31465172
61 + 31465111 = 31465172
73 + 31465099 = 31465172
103 + 31465069 = 31465172
139 + 31465033 = 31465172
181 + 31464991 = 31465172
199 + 31464973 = 31465172

Showing the first eight; more decompositions exist.
