Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489304, here are decompositions:

61 + 31489243 = 31489304
127 + 31489177 = 31489304
157 + 31489147 = 31489304
241 + 31489063 = 31489304
277 + 31489027 = 31489304
313 + 31488991 = 31489304
373 + 31488931 = 31489304
397 + 31488907 = 31489304

Showing the first eight; more decompositions exist.
