Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495412, here are decompositions:

61 + 31495351 = 31495412
79 + 31495333 = 31495412
139 + 31495273 = 31495412
199 + 31495213 = 31495412
241 + 31495171 = 31495412
349 + 31495063 = 31495412
409 + 31495003 = 31495412
433 + 31494979 = 31495412

Showing the first eight; more decompositions exist.
