Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465304, here are decompositions:

61 + 31465243 = 31465304
127 + 31465177 = 31465304
151 + 31465153 = 31465304
181 + 31465123 = 31465304
193 + 31465111 = 31465304
271 + 31465033 = 31465304
313 + 31464991 = 31465304
331 + 31464973 = 31465304

Showing the first eight; more decompositions exist.
