Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461496, here are decompositions:

83 + 31461413 = 31461496
317 + 31461179 = 31461496
347 + 31461149 = 31461496
383 + 31461113 = 31461496
449 + 31461047 = 31461496
569 + 31460927 = 31461496
617 + 31460879 = 31461496
659 + 31460837 = 31461496

Showing the first eight; more decompositions exist.
