Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520654, here are decompositions:

37 + 31520617 = 31520654
73 + 31520581 = 31520654
127 + 31520527 = 31520654
157 + 31520497 = 31520654
163 + 31520491 = 31520654
283 + 31520371 = 31520654
337 + 31520317 = 31520654
421 + 31520233 = 31520654

Showing the first eight; more decompositions exist.
