Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495112, here are decompositions:

3 + 31495109 = 31495112
109 + 31495003 = 31495112
163 + 31494949 = 31495112
193 + 31494919 = 31495112
331 + 31494781 = 31495112
349 + 31494763 = 31495112
421 + 31494691 = 31495112
433 + 31494679 = 31495112

Showing the first eight; more decompositions exist.
