Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503098, here are decompositions:

37 + 31503061 = 31503098
139 + 31502959 = 31503098
157 + 31502941 = 31503098
241 + 31502857 = 31503098
337 + 31502761 = 31503098
397 + 31502701 = 31503098
409 + 31502689 = 31503098
439 + 31502659 = 31503098

Showing the first eight; more decompositions exist.
