Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535672, here are decompositions:

79 + 31535593 = 31535672
331 + 31535341 = 31535672
409 + 31535263 = 31535672
439 + 31535233 = 31535672
499 + 31535173 = 31535672
541 + 31535131 = 31535672
613 + 31535059 = 31535672
661 + 31535011 = 31535672

Showing the first eight; more decompositions exist.
