Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540954, here are decompositions:

83 + 31540871 = 31540954
131 + 31540823 = 31540954
167 + 31540787 = 31540954
227 + 31540727 = 31540954
311 + 31540643 = 31540954
317 + 31540637 = 31540954
461 + 31540493 = 31540954
743 + 31540211 = 31540954

Showing the first eight; more decompositions exist.
