Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495594, here are decompositions:

3 + 31495591 = 31495594
5 + 31495589 = 31495594
71 + 31495523 = 31495594
83 + 31495511 = 31495594
101 + 31495493 = 31495594
113 + 31495481 = 31495594
131 + 31495463 = 31495594
191 + 31495403 = 31495594

Showing the first eight; more decompositions exist.
