Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495604, here are decompositions:

3 + 31495601 = 31495604
13 + 31495591 = 31495604
103 + 31495501 = 31495604
157 + 31495447 = 31495604
181 + 31495423 = 31495604
271 + 31495333 = 31495604
331 + 31495273 = 31495604
433 + 31495171 = 31495604

Showing the first eight; more decompositions exist.
