Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523126, here are decompositions:

7 + 31523119 = 31523126
13 + 31523113 = 31523126
73 + 31523053 = 31523126
139 + 31522987 = 31523126
379 + 31522747 = 31523126
409 + 31522717 = 31523126
433 + 31522693 = 31523126
457 + 31522669 = 31523126

Showing the first eight; more decompositions exist.
