Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504762, here are decompositions:

59 + 31504703 = 31504762
71 + 31504691 = 31504762
101 + 31504661 = 31504762
269 + 31504493 = 31504762
281 + 31504481 = 31504762
389 + 31504373 = 31504762
659 + 31504103 = 31504762
953 + 31503809 = 31504762

Showing the first eight; more decompositions exist.
